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

The Fuel Efficiency of Law Enforcement Vehicles

I live in Durham, where the ELF is built. The ELF is a pedal-and-electric-powered reverse tricycle with an egg-shaped body and a solar panel roof. It is certainly unique. A 360-degree view is available here. Organic Transit, the company that builds the ELF, states that it “gets the equivalent of 1800 m.p.g.”

What does this have to do with criminal law? Well, the company recently introduced the Tactical ELF, designed to “give[] [law enforcement agencies] the tactical advantage for community policing.” An endorsement from Duke’s campus police comments that “It’s like a small patrol car.” I doubt that the ELF is going to be a mainstream law enforcement vehicle anytime soon, but it did get me thinking about the fuel efficiency of law enforcement vehicles generally. This post summarizes what I learned.

Not So Fast:  Dismissal of DWI Charges for Failure to Schedule Trial in 30 Days  

Defendants who drive while impaired while their licenses are revoked for another impaired driving offense or who drive while impaired without a license and without car insurance risk more than criminal prosecution. The vehicles they drive must be seized, and, if they are convicted, will be ordered forfeited. To speed up the forfeiture process, DWI cases involving vehicle forfeitures must be scheduled within 30 days of the offense. But they rarely, if ever, are. Are defendants entitled to relief when the statutory scheduling directive is ignored?  And can that relief come in the form of the dismissal of criminal charges?

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 the2Was the Checkpoint Reasonable 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?

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.

Updated Paper on Traffic Stops

I’ve recently updated my paper on traffic stops. As before, it covers stops from start to finish, including the legal standard for making a stop, the length of a stop, and investigative techniques that may be used during a stop. I may need to update it again after the Supreme Court decides United States v. … Read more

When Reasonable Suspicion Is Dispelled

A traffic stop is valid if it is supported by reasonable suspicion. During a valid traffic stop, an officer may demand the driver’s license and registration, may run a computer check based on those documents, and so on. But what if the reasonable suspicion supporting the stop dissipates soon after the stop is made?
