There is no scenario in life where I would ever call a LEO for assistance.
Go ahead, call for help, just don’t be surprised when you end up dead.
If you ever have to use justifiable deadly force against another human, would you call the police? Are you going to shovel and shut up? What if a witness calls the police and police start arriving near you? Are you going to play nice with the police or are you going to flip out into your usual paranoia and “defend yourself” from ending up dead?
What if you are in a situation where deadly force is not warranted, say you witness a vandalism against your vehicle in a parking lot. What are you going to do?
Use deadly force anyway? (See above.)
Forget about it? (Your insurance company would want a police report.)
Beat the miscreant up, take restitution in the form of his personal possessions, and leave?
Make a “citizen’s arrest,” throw the guy in the back seat of your car and try to book him into the nearest jail?
Throw him in the back seat of your car and lock him up in your basement to serve out his time?
You really need to step away from the Internet and whatever news sources that you rely upon. They are giving you a warped sense of reality, where the exceptions are your perceived norm.
