How many of those murders go unsolved because the police do a half ass investigation? You claim that folks won't "snitch", they don't snitch because they are AFRAID of the retaliation against them because they police damn sure aren't going to do anything to protect them. When you run your mouth at least know what you are talking about..
Unless someone is willing to snitch, what do you want to detectives to do to resolve the case. Activists also get pissed off if the detectives bring in the suspects and squeeze a confession out of them.
Remember this, and never forget, the CP5 CONFESSED to the fucking crime. They weren't "framed", they admitted they did it. And the libs still bitched and whined.
They confessed after being "squeezed" as you call it. Think of the countless black men who have been framed in the same manner.
