It's amazing that people can comment on the police getting away with murder and say it's the police who aren't treated fairly. The police should be questioned every step of the way. Society gives them a lot of power and power is easily abused. We need to make sure the police are held to account for that abuse. Are they questioned every step of the way? Well, you might have heard about this case where a police officer strangled a man to death, was filmed, had zero justification and was not charged for it.
Actually the Capt. makes a good point. Every occupation has it's share of F**k ups be it doctor, plumber or preacher. Much of the police's contact is with the lowest dregs of society, the pimps, pushers, the scammers and sometimes when you are called a pig often enough and your face spat on you wonder if it's all worth it. There's probably 10%-15% of the force who shouldn't be there, but they are hard to identify when they first go for training and by the time it's detected many $thousands have been invested in them. I do believe for the first five years they should be issued with a bicycle and a flashlight until they can prove themselves.
