Jag, there are certain things that are not going to change.
The cops are like any other street gang. I have friends who are cops and they are no different than the bloods, latin kings, vatos locos, mexican mafia, or the crips. However, they have the judges, the DA, each other, and the law behind them.
The cops have to establish their street cred in public or no one will obey them or respect them. They want to be feared, not loved.
I'm not saying its right, but its what goes on.
You challenege a cop in public, at least where I am from, you getting a beat down.
