I didn't realize that was a legitimate question. Of course you should help people in need when you're capable... if you're carrying, of course it involves using your gun. Using your gun and shooting it are not always the same thing. That is something I'm sure you're trained on. I'm plenty aware of due process and I used the word pickpocket instead of robbery because I'm quite sure of the difference. Your original post read that all criminals should be shot dead. I'll chalk it up to being lost in translation. Good day to you, sir.
If you a pull a gun you intend to use it. You my friend have proven you have zero knowledge on the subject. Drawing a firearm with intent to scare is a slippery slope.
