Yesterday, the Supreme Court decided Rodriguez v. United States, an important traffic stop case that changes North Carolina law as it pertains to certain drug dog sniffs, and perhaps other investigative techniques as well.
Search and Seizure
Hair Analysis Under a Microscope
Over the weekend, the Washington Post ran a story that begins as follows:
The Justice Department and FBI have formally acknowledged that nearly every examiner in an elite FBI forensic unit gave flawed testimony in almost all trials in which they offered evidence against criminal defendants over more than a two-decade period before 2000.
Of 28 examiners with the FBI Laboratory’s microscopic hair comparison unit, 26 overstated forensic matches in ways that favored prosecutors in more than 95 percent of the 268 trials reviewed so far, according to the National Association of Criminal Defense Lawyers (NACDL) and the Innocence Project, which are assisting the government with the country’s largest post-conviction review of questioned forensic evidence.

State v. Fizovic and Searching Cars for Alcohol
Author’s Note: This post has been modified from its original version in response to a helpful comment by a reader.
An officer sees a man drink from a can of beer while the man drives through a public parking deck. The officer stops the man’s car and sees the beer bottle can in plain view. He then asks the man to step out of the vehicle. May the officer open the car’s console to search for additional evidence?
Law Enforcement Use of Drones
Drones are remote-controlled aircraft. They can be equipped with cameras, and may be useful for surveillance. Does the use of drones by law enforcement officers raise any legal concerns?
The short answer is yes, in at least four ways.

Georgia Supreme Court Holds that Implied Consent Is Not Actual Consent
Prosecuting impaired drivers in Georgia just got a little bit harder. The Georgia Supreme Court held last week in Williams v. State, __ S.E.2d __ (Ga. 2015) that the mere fact that a DUI suspect agreed to allow officers to withdraw his blood–after being told that Georgia law required him to submit to testing and that his driver’s license would be revoked for a year if he refused–did not establish the sort of voluntary consent necessary to excuse the Fourth Amendment’s warrant requirement. Is this a watershed moment in implied consent law?
Drug Dogs and Checkpoints
I’ve had several questions about the role of drug dogs at motor vehicle checkpoints. The details are below, but a quick summary of the law is as follows:
(1) Officers can’t lawfully run drug dogs around every vehicle stopped at a checkpoint
(2) Officers can lawfully run drug dogs around cars that are pulled out of line for additional investigation, so long as the use of dog doesn’t substantially lengthen the stop

Keeping It between the Lines
Officer Fife is driving one car length behind Briscoe Darling at noon on a sunny day when he sees the tires on the right side of Darling’s car touch the fog line that borders Darling’s lane to the right. Darling drives on the fog line for a couple of seconds before his tires re-enter the unmarked portion of the lane. A half mile later, Darling’s tires again touch the fog line for a few seconds.
Officer Fife is driving one car length behind Charlene Darling at noon on a sunny day when he sees the tires on the right side of Darling’s car cross over the fog line that borders Darling’s lane to the right. Darling immediately moves her car back into the unmarked portion of the lane.
Officer Fife is driving one car length behind Mitch Darling at 9 a.m. on a cold winter morning when he sees the tires on the right side of Darling’s car cross over the fog line that border’s Darling’s lane to the right. After a few seconds, Darling moves his car back into the unmarked portion of the lane. Officer Fife is aware that the road the two are traveling is icy in spots.
Officer Fife is a stickler for compliance with motor vehicle laws. He believes it is his duty to stop anyone who commits a traffic offense, no matter how minor. Which Darling or Darlings may he lawfully stop, and why?

State v. McDonald Provides Useful Primer on Checkpoints
The facts. A detective with the Charlotte-Mecklenburg Police Department writes a plan for a checkpoint to be conducted later in the evening. The plan states that the checkpoint will be established at the intersection of Ashley Road and Joy Street in Charlotte, NC. The plan states that the checkpoint’s purpose is to increase police presence in the targeted area while checking for driver’s license and vehicle registration violations. The plan further states that all vehicles traveling through the checkpoint must be stopped unless the officer in charge determines that a hazard has developed or an unreasonable delay is occurring. If that situation arises, all vehicles must be allowed to pass through until the hazard or delay is cleared.
The checkpoint is conducted from 12:34 a.m. to 1:52 a.m. on the designated evening. Every vehicle that travels through the checkpoint is stopped, and the officers ask every driver for his or her driver’s license.
The question. A passenger in a car stopped at the checkpoint moves to suppress evidence obtained during the stop and subsequent search of the car, alleging that the checkpoint was unconstitutional.
If you were the court, how would you rule?
North Carolina Supreme Court Upholds Warrantless Seizure of Drugs on a Home’s Curtilage
The Fourth Amendment protects the home as well as its curtilage, which is defined as the area immediately surrounding the home and associated with it. Recently, the North Carolina Supreme Court in State v. Grice, 2015 WL 304075 (Jan. 23, 2015), was confronted with a Fourth Amendment issue involving the curtilage. The court held, reversing the court of appeals, ___ N.C. App. ___, 733 S.E.2d 354 (2012), that officers who were validly on the curtilage of a residence to conduct a knock and talk did not violate the Fourth Amendment when they saw marijuana plants 15 yards away on the curtilage and warrantlessly seized them.

Beating the Rap . . . But Taking the Revocation
Myra Lynne Combs beat her DWI charges in court. The trial court held that the officer who stopped her didn’t have a lawful reason to do so. So the trial court suppressed all the evidence resulting from the stop, and the State dismissed the charges. But Combs’ license was revoked for a year anyway based on her refusal to submit to a breath test after she was arrested. Combs didn’t think that was right, so she took her case to the state court of appeals.
