"Getting the drop on him has everything to do with it. Action is faster than reaction."
Getting the drop on somebody is an expression. It means the advantage. It doesn't mean you automatically win the situation. Sure you want to use surprise, and action IS quicker than reaction. But reaction can be deadly too. Getting killed for my car stereo? No thanks. I am an LEO and I would still stay in my house until "on duty" police officers get there. If this person decides he wants to come in my house before then...well that's a different story.
If not you, then who?
