What Everyone Needs to Know about Knock and Talks

Knock and talks are a common, useful, and sometimes controversial law enforcement tool. I thought that I would put together a post that summarizes the principal legal issues that they present.

Knock and talks are generally permitted. The Supreme Court of the United States has ruled that there is an “implicit license” that “typically permits [a] visitor to approach [a] home by the front path, knock promptly, wait briefly to be received, and then (absent invitation to linger longer) leave.” Florida v. Jardines, 569 U.S. 1 (2013). This implied invitation applies to law enforcement officers just as it does to other citizens. “Thus, a police officer not armed with a warrant may approach a home and knock, precisely because that is no more than any private citizen might do.” Id. (internal quotation marks and citation omitted).

Where an officer may go. “[T]he knock and talk doctrine does not permit law enforcement to approach any exterior door to a home. An officer’s implied right to knock and talk extends only to the entrance of the home that a reasonably respectful citizen unfamiliar with the home would believe is the appropriate door at which to knock.” State v. Huddy, __ N.C. App. __, 799 S.E.2d 650 (2017). In most cases, that means the front door. See, e.g., State v. Stanley, __ N.C. App. __, __ S.E.2d __, 2018 WL 2207928 (discussed in this prior post; holding that an officer exceeded the permissible scope of a knock and talk by approaching the back door of a residence, notwithstanding the fact that several controlled buys had been conducted at that door). An officer can use appropriate driveways and walkways to reach the front door, but generally can’t deviate from those paths to explore the curtilage.

When an officer may go. There is no implied license for visitors to approach a home in the middle of the night while the occupants are asleep. Accordingly, “a number of courts have found late-night inquiries unreasonable because of the societal expectation that members of the public would not knock on one’s front door in the middle of the night.” State v. Hargett, 795 S.E.2d 828 (2017) (unpublished) (apparently endorsing the principle but finding a late night knock and talk reasonable where a person had just entered the house and officers could smell burning marijuana coming from the home as these factors indicated that people were awake and active in the house). See also People v. Frederick, 895 N.W.2d 541 (Mich. 2017) (holding that police exceeded the permissible scope of a knock and talk by approaching homes at 4:00 a.m. and 5:30 a.m. while all occupants were asleep). Although courts have rejected time-based bright lines, knock and talks between 11:00 p.m. and 6:00 a.m. may receive increased scrutiny.

What an officer may bring. An officer who brings a drug dog, a metal detector, or other detection or inspection tools along to use during a knock and talk exceeds the scope of the implied invitation to approach the home. Florida v. Jardines, 569 U.S. 1 (2013) (“[I]ntroducing a trained police dog to explore the area around the home in hopes of discovering incriminating evidence is [beyond what a private citizen might do]. There is no customary invitation to do that.”).

How an officer may announce his or her presence. A social visitor would not be expected to bang on the door loudly and for a protracted period of time, or shout out demanding entry. Accordingly, there is likely some limit to how assertively and persistently an officer may knock. See United States v. Jerez, 108 F.3d 684 (7th Cir.1997) (ruling that an interaction became an involuntary seizure rather than a consensual knock and talk when officers went to a quiet motel room after 11:00 p.m., knocked on the door for three minutes, called out “police” and “open up,” then proceeded to knock loudly on the room’s window for another minute or two). There is no simple way to determine how much knocking is too much, and the answer may depend on factors like the time of day, the size of the residence, whether the officer hears movement inside, and other factors. Cf. United States v. Carloss, 818 F.3d 988 (10th Cir. 2016) (in a case in which officers knocked for “several minutes” but not “aggressively,” the court “decline[d] to place a specific time limit on how long a person can knock before exceeding the scope of this implied license”).

Interacting with the occupant. An occupant is not required to answer the door. If one does so, the officer need not advise the occupant of his or her right to refuse further interaction with the officer. See generally Schneckloth v. Bustamonte, 412 U.S. 218 (1973) (“One alternative that would go far toward proving that the subject of a search did know he had a right to refuse consent would be to advise him of that right before eliciting his consent. That, however, is a suggestion that has been almost universally repudiated . . . and we think, rightly so.”). However, the fact that an occupant answers the door does not mean that the occupant has consented to an officer entering the home. See, e.g., United States v. Sabo, 724 F.3d 891 (7th Cir. 2013) (noting that “one does not consent to the government entering his home by simply answering the door,” but finding that an occupant consented to an officer’s entry when he responded to the officer’s request to enter by stepping back and to the side, leaving the door open).

What if an officer sees contraband? During a knock and talk, an officer may see contraband or other incriminating items. Generally, “an officer must have a lawful right of access to any contraband he discovers in plain view in order to seize it without a warrant.” Collins v. Virginia, __ U.S. __, __ S. Ct. __, 2018 WL 2402551 (May 29, 2018). For contraband located inside a residence, a right of access might arise through an occupant’s consent to entry or through exigent circumstances, such as when an officer develops reason to believe that an occupant is attempting to destroy or to consume the contraband. See, e.g., Kentucky v. King, 563 U.S. 452 (2011) (holding that exigent circumstances can justify a warrantless entry to prevent the destruction of contraband even when the exigency is created by an officer knocking on the door). Otherwise, a warrant is required to enter the residence. For contraband located outside the residence, the Supreme Court of North Carolina has held that “[t]he presence of . . . clearly identifiable contraband justifie[s] walking further into the curtilage” to seize the contraband, even without a warrant, consent, or exigent circumstances. State v. Grice, 367 N.C. 753 (2015). However, the may be some tension between Collins and Grice into question, and a cautious officer may wish to seek consent or a warrant before cutting across the curtilage to make a seizure unless exigent circumstances exist.

What if an officer smells contraband? [This section was added in response to reader comments.] Suppose that an officer detects the odor of marijuana coming from inside a residence during a knock and talk. The odor provides probable cause to believe that someone inside is possessing marijuana. Does it also provide exigent circumstances supporting a warrantless entry and search for the drugs? North Carolina’s appellate courts have generally ruled that it does. See, e.g., State v. Marrero, __ N.C. App. __, 789 S.E.2d 560 (2016) (exigent circumstances supported officers’ entry during a knock and talk where, among other factors, the officers had been told that the residence was a “marijuana plantation” and the officers smelled unburned marijuana during the knock and talk; it was “objectively reasonable to conclude that . . . defendant would destroy evidence when [the officers] left the scene to obtain a search warrant, especially given the ready destructibility of marijuana”); State v. Corbitt, 217 N.C. App. 400 (2011) (holding that an officer’s “detection of the odor of burning marijuana and observance of . . . furtive movements in the residence [after the officer knocked on the door] were sufficient to support a reasonably objective belief that evidence of criminal activity was about to be destroyed,” which supported a warrantless entry). But see United States v. Mongold, 528 Fed. Appx. 944 (10th Cir. 2013) (unpublished) (exigent circumstances did not support a warrantless entry where officers “smelled marijuana” during a knock and talk; although there was probable cause to believe that marijuana possession was ongoing, that is not a sufficiently serious crime to support exigency). A cautious officer may limit the scope of any warrantless entry and search to securing the premises while a warrant is obtained. See State v. Tripp, 52 N.C. App. 244 (1981) (“So long as no general warrantless search is undertaken, when there is probable cause to believe that evidence is located in a house and a likelihood that the occupants will remove or destroy it pending issuance of a warrant (i. e., exigency), it is permissible for an officer already legitimately on the premises to secure the area against removal of property pending issuance of a warrant.” (citation and quotation marks omitted)).

Effect of “no trespassing” signs. The posting of a “no trespassing” sign is a pertinent factor when analyzing a knock and talk, but does not necessarily revoke the implied invitation to approach the house. In State v. Pasour, 223 N.C. App. 175 (2012), the court stated that “a homeowner’s intent to keep others out and thus evidence of his or her expectation of privacy in an area may be demonstrated by the presence of ‘no trespassing’ signs.” In other words, a sign “is evidence of the homeowner’s intent that the [area protected by the sign is] not open to the public.” Id. Yet the court recognized that the presence of a sign is “not dispositive,” and later relied on that statement in State v. Smith, 246 N.C. App. 170 (2016) (stating that “we are not aware of any court that has ruled that a sign alone was sufficient to revoke the implied license to approach” a residence and finding that ambiguous evidence of a “no trespassing” sign on the defendant’s property did not preclude a knock and talk). See also United States v. Carloss, 818 F.3d 988 (10th Cir. 2016) (collecting cases and ruling that “no trespassing” signs “posted around the house and on the front door . . . would not have conveyed to an objective officer that he could not approach the house and knock on the front door seeking to have a consensual conversation with the occupants” as such signs are not “talismanic” and do not clearly exclude those with legitimate business at the property such as “the mail carrier, pizza deliverer, or police officer”).

Other issues? Are there other issues that arise during knock and talks? If so, please post a comment and I’ll try to address them.

  1. Can you please expand upon this to include the situation where officers allegedly smell marijuana during a knock and talk? This seems to be a common occurrence and I would like to confirm my interpretation of how this is to be handled. Thanks.

    • I added a section to the post in an effort to address this comment. In a nutshell, the case law supports a warrantless entry based on the odor of marijuana, given its ready destructibility, but there is some authority suggesting that the scope of the entry should be limited to freezing or impounding the residence while awaiting a search warrant.

      • It seems like the Jardines case does not deter police from forcefully breaking into a home…who needs a dog when the officer can claim to smell alleged cannabis? No doubt there are some people stupid enough to open the door to police knocking when they are using cannabis, but even refusing to open the door is no bar to the police claiming, rightly or wrongly, that they smell what they believe to be weed, giving them the authority to hammer the door down and impound the residence. If a person refuses to open their door and the ;police really want to search anyway, what better way than claiming to smell weed? If none is found they will claim that the weed was flushed just before their arrival, and that they deserve immunity based on their ” good faith ” belief ” that they were right. If the sanctity of the home is dependent on the olfactory abilities of police, whether real or imagined or invented, the warrant clause is a dead letter in practical terms. When police want in and lack PC who really believes they are above false claims? To them the ends justify the means, even when the end results in no evidence. Now the ;police claim to have the same abilities as sniffer dogs…not a suprise since the Jardines case.

  2. Of course if people were educated about their rights, which is a subject seemingly never covered in schools, they could simply refuse to answer the door and record what the police do insofar as length of knocking, shouting, walking around the dwelling, etc. The curtilage issue is confusing; what signage WOULD suffice to convey the intent to bar anyone other than expected or invited guests? Private clubs post ” members only ” signs that convey exclusivity to all other than members. Do people have to fence a property and post signage that makes it clear that no one is to approach before being beyond knock and talks? Does a resident have to exclude ALL visitors to avoid evidence gathering visits from police? Someone with a PO box rather than home delivery and never orders pizza’s to be delivered no doubt would have to affirmatively, I am sure, somehow convey the expectation of privacy. How does a person without the financial or practical means to install fences with gates that remain locked along with explicit signage convey a desire to never be approached without prior permission? In my opinion ” knock and talks ” are usually conducted by aggressive and frustrated police who lack PC for a warrant and very much want to enter and arrest on that visit. Opening the door can lead to a claim, whether true or not, that ” weed ” is smelled so entry can be made, and one only has to watch YouTube to see police placing their foot in the threshold to deny the ability to close the door while the occupant is badgered to permit entry or allow interrogation.

    It should be taught to all: If you want to speak to the police, open the door and take your chances. If you do not, simply refuse to open it and document what the police do when denied your attention. It seems that the schools always teach responsibilities but not rights. The police by their very nature are intimidating and demanding and overcoming that to invoke rights takes knowledge and self assurance, which is what schools are supposed to provide. One should not have to earn a J.D. before knowing the rules.

    • If someone who is house sitting open the door and steps onto the porch to discuss the situation, do the Police have a right to search the home? I was on vacation and this very thing happened .. house was searched and property disturbed.

  3. An officer came to my mother’s house when I was not home. He did a knock and talk with police trickery. My little brother allowed him in as the officer stated ” that he was investigating phone scams. ” its like he asked if he could take a look at their phones. They shouldve said no not without a warrant. All because they were under the impression that he’s authority. My questions are. Was that illegal entry? I feel that it was because the DA who was involved omitted that part out. The Da also wrongfully convicted with prostitution. The text message read” I’d give you 200 dollars for a topless massage.” Including when they finally got a warrant. The evidence was circumstantial and fabricated as to appear everything connected to the phone. The phones he retrieved were not the phones that weren’t being used in unlawful acts. He wrote on the warrant the phone(s) he thought were the actually numbers. When the forensic analysis done on the phones came up N/A they used it any way as evidence. They didn’t retrieve any deleted messages, pics, contacts, etc.

  4. Can an officer enter the home with permission by a residents guest and not a resident? I’m a college student and I had a party. The cops came and I was in my room. A random girl let them inside. I went out to the cops in my house and asked them to leave because they were inside without a warrant and I did not allow them in. I got charged with two misdemeanors and they used excessive force on me to put me in handcuffs. My charges were for a fake id, which was accidentally presented to the cops by one of my friends, not me, I was handcuffed. The other charge was for resisting arrest. I did not resist, I have videos. I am most concerned with my initial question but would appreciate any advice or tips as well.

  5. I had an incident in my home where I called 911 for an ambulance. There was also a little scuffle between my 24 year old son and my husband. I watched my husband take some pills and was worried so I called. The police came before the ambulance and split all 3 of us up to get the story. While I was being questioned outside, on my porch with my door open, the officer proceeded to look into my home and then walked about 4 feet in for about a minute, then back out. He didn’t see anything suspicious. My question is: Are officers just allowed to walk inside your house, hoping to find something illegal? I told him to stop and he told me to shut up. He then went down to arrest my husband (for the scuffle – no injuries, it was over my son wanting to use the car. When he was arrested, the officer handcuffed him while he was sitting and the officer put his foot on his back and pressed hard. They said he was faking passing out. The paramedics arrived and told him to stop. They took his blood pressure and it was extremely low because of the pills he took (yes, that was not a smart thing to do). The cops decided not to charge him and he went to the hospital. I think pissed off cops do this to everyone, although more so to black people. I am disgusted that I called for help and was treated this way. My husband is fine today, the next day and is home. I encourage people to not call the cops unless of an extreme emergency! Try to handle family problems at home! I am in no way condoning what my husband did, but he needed mental help, not aggressive police!
