What if they’re a bunch of criminals dressed up like the police so that home invasion robberies are easier to pull off?
This is yet another reason why no-knock warrants ought to be abolished.
If the police are never allowed to bust in, guns at the ready, then you won’t have to worry about people pretending to be the police kicking in your door. If someone does kick in your door, you know that they’re criminals.
Instead of criminals who also happen to be the police.
