The 12-Minute Wait and the Dog
At 11:40 p.m., a patrol officer stops a sedan on Route 9 for a defective plate light. The driver is licensed and sober; the registration is valid; there are no warrants. The officer returns the documents and issues a written warning at 11:48, then asks for consent to search. The driver says, 'I'd rather not.' The officer keeps the driver at the roadside, calls a K-9 unit, and at 12:02 the dog alerts on the trunk. Officers find a locked toolbox containing a handgun and two magazines; the driver has no license to carry. The driver says, 'I told you no, you can't search.' The officer says he was 'waiting for the dog.' You are the captain reviewing the incident. The driver's attorney has filed a complaint and a motion to suppress. The stop was recorded on body camera. The K-9 unit was 14 minutes away. The officer's report says the driver was 'free to go,' but the video shows the officer standing in front of the door and saying 'hang tight.'
1. Evaluate the constitutionality of the continued detention under the Fourth Amendment and Article 14.

The continued detention is the problem. Under Rodriguez v. United States, 575 U.S. 348 (2015), a traffic stop may last no longer than reasonably required to address the violation and related safety concerns. The warning was issued at 11:48; the dog alerted at 12:02, roughly 14 minutes later. Once the warning was written and the driver was otherwise clear, the mission of the stop was complete. The driver refused consent. The officer needed reasonable suspicion of criminal activity to extend the stop, and the facts, a defective plate light, valid license and registration, no warrants, and a sober driver, do not supply it. The body camera undercuts the report: saying 'hang tight' while standing in front of the door is a seizure, not a 'free to go' encounter. Massachusetts Article 14 may be at least as protective, and the SJC has suppressed evidence where a stop was prolonged for a dog sniff without reasonable suspicion. The fact that the K-9 was 14 minutes away does not create suspicion; officer convenience is not the test.
2. Assess the firearm charge and whether the evidence likely survives.

The handgun and magazines are likely suppressed as fruit of the unlawful seizure. The Commonwealth might argue inevitable discovery through an inventory search, but that requires a lawful impoundment and a standardized inventory policy, not a pretext to search for evidence. It might also argue attenuation, but the causal link is direct: the alert occurred during the unlawful extension. The charge under G.L. c. 269, § 10(a), carrying a firearm without a license, may therefore fail even though the driver apparently lacked a license to carry.
The captain should not treat the constitutional issue as a technicality. The firearm may be returned or held per court order, and the DA must be notified of the suppression risk. If the driver had a prior disqualifying conviction, that does not cure the search. The correct question is whether the officers had independent probable cause before 11:48; the report does not show it. The toolbox being locked also matters: the opening of a closed container requires its own justification.
3. What supervisory, training, and report-integrity action should follow?
Read the worked answer
Supervisory action: (1) review the body camera with the officer and his union representative; (2) refer the report discrepancy to internal affairs for a truthfulness review, because 'free to go' boilerplate contradicted by conduct is a serious documentation problem; (3) require training on Rodriguez, consent, exit orders, and K-9 requests, including a script for ending a stop; (4) review the K-9 unit's call-out criteria so dogs are not requested as a fishing tool; (5) audit similar stops for a pattern; (6) notify the DA and ensure Brady/Giglio implications are assessed. Correct the report through a supplemental, not by altering the original. The officer should not be disciplined for exercising lawful discretion, but he can be disciplined for a false or misleading report if the investigation supports it. Document the training and the policy clarification.
