The only time a body cavity search would be allowed is after arrest or, of course, with a warrant.
Yes. If you are merely being detained they can search you for WEAPONS to insure their own safety, but not look for evidence. It’s not like this is some sort of secret thing that only constitutional attorneys know. That is probably part of the training in just about every police department. But many cops get lazy Especially when they don’t get called on this. And that is even more prevalent when they’re dealing with poor people who can’t afford competent council.
Police have always ben a mixture of good and bad, and so long as most police turn a blind “blue wall” eye to this sort of behavior, it will continue. Keep in mind when reading these stories that the police in this country didn’t suddenly go bad on us. But until recently, the stories of bad cops didn’t really get much traction, especially if the victims were people of color.
