Ok, earlier I was eating at my university's cafeteria, and got up to get some dessert. I left my bag with my $450 tablet and $80 case in it. I usually NEVER leave any of my stuff laying around (I take it with me no matter how short of a distance), but I was walking about 30 ft away, so I could still see my bag. I thought of a scenario that isn't really self defense, but more of a protection of property. Just note, this is a "what if" scenario, and I have no intention of being Billy Badass and escalating straight to potentially lethal force, if necessary. But what if I was in a public place and witnessed the theft of my property, like someone walking up and picking up my bag and starting to walk off. What would be the best approach to this scenario: A. Approach them in a serious tone and tell them to put the bag down (ideal approach, unless they are one of the tough guy types) B. Grab them by the shoulder and turn them around and tell them to drop it C. Some people would say go straight to brute force and knock them out, which I would see as an appropriate way to get the scumbag, but what if they are tougher/bigger than you are? I also think this could be a possible assault charge. D. What if you used approach A or B, and they reacted with brute force, could you fight back as self defense? Or if it escalated rather quickly... E. What if they were one of "those" types and pulled a weapon when you demand they return your property? I understand your life is more important than a $500 computer, but what if they intended to harm you (tried to stab you or shoot you), would you be allowed to draw a weapon and defend yourself in self defense (I don't see why not, if they tried to use lethal force against you, but some laws are iffy)? F. Now I do not advocate this, because it would be a use of excessive force and could cause MAJOR legal reprocussions, but what if you approached them, pulled a weapon, and demanded they return your property (again, I do not advocate this)? I mean if they intentionally stole your stuff, like they knew you were there. Also would work with car theft/car break in.
