I'm not big on collective guilt, and that is an understatement, but when "the police" shit everywhere, then they attract people with a bone to pick (to mix metaphors mercilessly).
Here's my point and prediction, which I was afraid to make for months, for risk of appearing to promote "blowback:" The abusive behavior of police in our country will lead to more fatal attacks on police. People can only put up with so much shit, and I am surprised that more LEOs have not been justifiable killed by their victims or bystanders (while police stole from, assaulted, and murdered fellow citizens), but the pipers call needs a payer, and too many LEOs are tooting their horns begging for blowback.
In no way do I endorse premeditated murder, or political killings. But the madness of cops running around with a false belief in an entitlement to run roughshod over other civilians' rights, "forcing" statutory and ordinance rules, and a false faith in the rule of (manufactured) law will lead to more LEOs deaths - and an even more entrenched bunker mentality among them. And this is even more ironic, because law enforcement is NOT the most dangerous job in America.
Clearly those two beasts in Las Vegas chose an enemy to facilitate their own destruction, but cops are too often making themselves false demigods. They have drank the professional LEO KoolAid that they are separate from other civilians, that they are the sole legitimate practitioners of violence, that they can use violence to force rules for victimless crimes, and that noncompliance with their demands is a crime - to name just a few outrages.
Individual cops do themselves a great service, when they treat others with respect, focus on real crimes, and question others up the chain of command that demand enforcement of victimless "laws."
I want to reiterate my opposition to collective guilt, despite the fact that it is probably true that the sentiment might not be mutual. But cops need to understand that bad eggs and institutional-moral decay with reflect poorly on them - individually.
They aren't all pure as the driven snow when it comes to protecting individual rights, but here are a few organizations that address police violations of rights - and the Constitutionality of police and government actions:
Constitutional Sheriffs and Peace Officers Association (CSPOA)
American Civil Liberties Union (ACLU)
National Rifle Association (NRA)
