If the job of the police is not to protect, then why do they put "to serve and protect" on a lot of cop cars?
I think it would be implicit that the job of the police is to protect the citizens, if not, WHY THE HELL HIRE THEM!!!!
If I hire an armed guard to protect my place of business, and he does nothing when the place gets robbed, I think I would be in my rights to sue him.
