Knock and Talk
When the police don’t have enough evidence to get a search warrant, they sometimes employ a procedure they have nicknamed “knock and talk” to investigate further. Courts have ruled that a police officer has the same right as an everyday citizen (for example, a Girl Scout selling cookies) to visit your house, knock on your front door, and ask to speak with you. Unfortunately, abuses of the “knock and talk” technique are now rampant. In one case, when no one answered the front door, the police started walking around the property knocking on back doors and side doors until they spotted some marijuana through a window in the back of the house.
In December 2015 the ACLU of Michigan filed a friend-of-the-court brief in the Michigan Supreme Court, arguing that the police need a warrant before they roam around your back yard peering into your windows. In July 2016 we filed another friend-of-the-court brief in a similar case before the Michigan Supreme Court, arguing that a so-called “knock and talk” violates the Fourth Amendment when it is conducted in the middle of the night.
