If you are a "good" police officer, or family of a "good" officer whom you vigorously defend, ponder this please...
When was the last time you arrested one of the bad officers in your department?
When was the last time you turned that guy in to your supervisors?
You know, the guy who chokes handcuffed victims, shoots family dogs, writes needless tickets, etc.?
(For family, when was the last time your loved one did this?)
If you haven't... then you are not a "good" cop.
You are just as guilty as the bad cop you refused to arrest or turn in to supervisors.
