It seems the police are losing sight of why they're hired, namely, to enforce law as deemed necessary and to keep the peace.
They are not hired to be a military presence in lieu of a REAL military presence (as forbidden by the Constitution) in the United States, although of late and after reading account after account of the militarization of both the police and their mission, I'm beginning to wonder if this might be someone's way of getting around the rights and protections of the citizenry.
I read an article that explained why many cops act like they do. The Supreme Court about 50 years ago gave the police permission to do almost anything if they think their life is in danger. With bad cops abusing the system and getting away with it more cops started doing it.
I was restrained in my own home by ICE during a raid for a person that did not live in the house and seldom visited. I rented the basement and they were looking for the son of my landlord. I ended up in handcuffs until they decide they were wrong. The oldest agent realized they were making a mistake. ICE had not done their homework and I ended up in handcuffs. I would guess there was nothing in their reports about me being put in restraints.
That said their a law enforcement officers that do a great service for the community.
