The SCOTUS ruled a long time ago the police don't have a duty to protect anyone or even respond to emergencies.I always carry a 9mm.
Have a 12 gauge in the house with 00buck waiting for anyone that wants to come through the door. Police do not stop crime they just show up after the fact to take a report.
I don't know if I'm allowed to post links but I'm going to do it anyway and let an admin or mod sort it out if it's not allowed.
The police 'protect and serve' the state, not you:
