Why did you glare at the man with your fixed stare? Why did you verbally confront him? Why did you then physically confront him, escalating your verbal confrontation? What good did that do you, or that man, whom you infuriated for no good reason, only to prove yourself stronger? Now you are obviously contemplating shooting someone over a confrontation like the one you describe, which you could have avoided entirely. Let me repeat, you could, and should have, avoided that confrontation entirely. If you shoot someone whom you could have easily avoided, you will go to jail and lose your privilege to own firearms forever, and you would deserve it.
