In most DWI cases, the State obtains evidence of a defendant’s alcohol concentration from a breath-testing machine. In order for the results of such a breath test to be admissible at trial, the State must follow the procedures set forth in the implied consent statutes, G.S. 20-16.2 and G.S. 20-139.1. Those statutes require, among other things, that a suspect be advised of his right to refuse testing and the consequences of such a refusal and that he be afforded an opportunity to contact a witness to observe the testing. Less frequently, a law enforcement officer will request that a person charged with an implied consent offense such as impaired driving submit to a blood test. Like the breath test results, the analysis of the defendant’s blood sample obtained pursuant to such a request is admissible at trial only if the State follows the procedures set forth in the implied consent statutes. If the request for a blood test follows an earlier request for a breath test, then the officer must re-advise the suspect of his implied consent rights before asking for consent. None of these rules apply, however, when blood is withdrawn pursuant to a search warrant.

Book on Digital Evidence Now Available
I’m happy to announce that my book on digital evidence is now available. There are five chapters, covering (1) search warrants for digital devices, (2) warrantless searches of digital devices, (3) law enforcement access to electronic communications, (4) tracking devices, and (5) the admissibility of electronic evidence.
Supreme Court Rejects “De Minimis” Extension of a Traffic Stop to Deploy a Drug Dog
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.
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?
