What does MN v. Wiegand specify about the duration of investigative detentions?

The ruling in MN v. Wiegand specifies that investigative detentions must be temporary in nature. This guideline emphasizes that such detentions should not last longer than necessary for officers to achieve the purpose of the stop, which is to confirm or dispel any suspicions of criminal activity. The requirement for a temporary duration serves to protect individual rights against unreasonable seizures, in accordance with the Fourth Amendment.

In this context, an investigative detention is meant to be brief and should only extend as long as it takes to address the officer’s concerns. Officers are expected to act diligently; any unnecessary prolongation without justification could render the detention unlawful. Thus, the principle established in this case reinforces the idea that while law enforcement has the authority to detain individuals for investigative purposes, they must also respect personal liberties by keeping those detentions brief and purposeful.
