Police Officer Shoots 14-Year-Old After Just a 0.6-Second Warning NowThis

10. Training

This is how they are trained in the police academy and by their training officer. When making an arrest shout "stop resisting" so that when you get sued witnesses will testify that you warned the subject and you are then completely justified when you break their arm.
After all you need to practice using that really cool (sarcasm) arm breaking technique you leaned in the academy! This is also why cops were shooting puppies so much - next best thing to shooting a person. Once you get your first kill you become a hero to your fellow cops.
