I try to put myself in the scenerio. I am walking down the street and minding my own business and not breaking the law. Some (non-LEO individual) starts following me and hassling me, I am going to get real defensive and make him stop, period. Ask yourself, in this situation, wouldn't you?
No, I wouldn't. Because of my maturity and experience level my mind is running through 100 different scenarios while this dude is trying to jack with me. The one thing that you've failed to think about is that he wants you to react. He wants you to play the tough guy. Cause he knows you'll get tunnel vision so bad that you fail to see his three gang bangin' homies
that have been also following in the shadows. After you engage this guy the other three are gonna make you regret that decision. We got too many tough guys on here that can't see the bigger picture. As they say "Pride goeth, before the fall".
