This is, apparently, the kind of thing that was happening in Watertown, Mass during the hunt for the young Islamic terrorist jackass who doesn’t deserve to have his name mentioned on this website. If this is what a voluntary search looks like, I’d hate to see what would happen if you expected to see a search warrant.
The fourth amendment says:
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
I realize there was a man hunt going on, but if this is how we’re going to treat our fellow citizens at their own front door then the terrorists have already won.
