GURPS - Cops

From their website:

"Out on the streets, it's you, your service revolver, and your partner. Remember to wear your vest. The day you forget it is the day some punk pops a cap in your gut.

GURPS Cops is an in-depth look at the world of the police officer. Players can recreate their favorite cop show with details about police forces through history, different sorts of police jobs, what investigations are like in the real world . . . through the courts and sentencing. This is a gritty, no-punches-pulled book for the player and GM who want a realistic game."

Not from their website (but it had to be done):

"Bad boys, whatcha want
Watcha want, whatcha gonna do?
When sheriff John Brown come for you
Tell me whatcha wanna do, whatcha gonna do?
Yeaheah

Bad boys, bad boys whatcha gonna do?
Whatcha gonna do when they come for you?
Bad boys, bad boys whatcha gonna do?
Whatcha gonna do when they come for you?"
