You simply can’t rely on the police for you personal protection as this article via Says Uncle shows. Two police officers in San Pablo stood by and watched as a gun name on a bridge killed two people. They made no effort to stop the gun name, apprehend him, or even get the license plate number of the criminal’s vehicle. They did radio for backup and block traffic from entering the bridge though, I guess that earns them a point out of 100 possible points.
Another thing to note is the amount of time it took to kill the two men:
The attack lasted less than half a minute.
So even if the police will protect you if they aren’t within 30 seconds travel distance you can be totally boned.
Remember people you are responsible for your own personal protection. Nobody is going to do it for you.
