Everytime I speak the truth about cops, someone will object and tell me "there are good cops!"
No. There are not.
As I saw someone say a while back- and I wish I could remember where I saw it and who said it- there are "nice cops", but no "good cops".
A "nice cop" is one who treats you in a non-cop manner. Who holds the door for women, stops to help a stranded traveler, gives a thirsty dog a drink. Things any of us would do if we are decent people. He is nice because of who he is, and what he is doing at the moment, not because of what his job might be.
But, that same "nice cop", as soon as he enforces ONE counterfeit "law" is no longer a good person. He is being a cop. He might still do "nice" things while on the job, but the overwhelming majority of that "job" is inflicting evil upon people.
Most bad guys can't spend all their time being evil. It's too much work and would cripple their ability to live among friends and family- if they could even keep friends and family. They have to be nice to those around them most of the time, no matter what they do when they target those they consider to be "other" or "less-human". Because of this fact, you can have nice mobsters, nice muggers, and nice rapists, but none of them can be "good".
And neither can any cop. The "job" eliminates that possibility completely.
