Remember, criminals are not above getting SWAT-like outfits and calling themselves the police.
I also recall some guys dressing up as "Bail Enforcement Officers" and
raiding someone's home. Not sure if they were BGs doing dress-up or
some actual bounty hunters gone rogue. In any case, they weren't
doing bail enforcement and it was a home invasion/robbery.
Again, you have a situation with guys breaking into your house in tactical
gear, pointing weapons, and barking orders as if they had some authority.
Bad thing for you to find out it's BS after the fact. We've also had some
reports of the BG driving a car that looks like the police and pulling women
over around here --again. I've heard of this in 2 of the last 3 states I've
live in. Happens late at night on the country road. Only advice I can give
is call 911 the second the lights come on behind you and have dispatch
verify that an officer is actually pulling you over. Keeps everyone in
the loop.
I'm not worried about an accidental no-knock at my place since most people
can't even find my house with directions, a satellite photo, and MGRS
coordiantes --during the daytime!
