people are under some sort of misguided impression that the police are there to protect you. They are not your body guards, and will not protect you unless they happen to witness someone attacking you. The rich and powerful have body guards, you are responsible for your own safety and self defense, even if you're stripped of your 2nd amendment rights.
Police are 'law enforcement" officers. After you are stabbed, beaten, raped, robbed, killed, they will show up. Depending on the circumstance, they may write up a cute report and send you on your way or attempt to catch the criminal that assaulted (past tense) you.
