To be fair to them, they used to. Then they were hung out to dry by the forces of political correctness. Real cases of police abuse were used as a bloody shirt to hamstring police officers who were just doing their job - "take out the garbage", as you put it.
It's tragic, but a lot of the "brotherhood" code of silence in police forces is in place to prevent them from being jumped on by guilty opportunists with a convenient bloody shirt. Unfortunately, the code of silence does cover up real cases of police abuse - but it does draw a line that fends off "Mr. Mistrial" from walking all over everybody.
Let’s be honest and admit that the police focus almost all of their energy on the war on drugs, because that is where the money is. half of all murders go unfolded but if you have pot in their home then they will do their level best to find it
And to be quite honest, with ccw, we only need the cops to pick up the garbage. When seconds count, police are only minutes away. We as citizens have a right and an obligation to defend ourselves. Courts have ruled that police are not responsible for our protection. Bounty hunters are better that police at catching criminals as well.
