I guess that pretty much shows that my simplistic little framework is wrong. I'm not too big to admit a mistakeBut, there is an easy way to show that Texas sees it a little differently than you do. Under 31.03, the penalty for theft is automatically upgraded to a state jail felony if the item is stolen from a person or corpse.
I still think that the fear element in the robbery definition is important to CHL holders. Just because someone doesn't harm you or make an explicit threat while taking your possessions, their actions and demeanor can cause a reasonable person to fear injury. In that case, I believe we would be dealing with a robbery. And robbery is one of the offenses that justifies deadly force.
At any rate, I didn't mean to hijack the thread. I just think it's an interesting conversation and I believe that it pertains to the original post as to what actions would be justified in the situation described. Personally, I think the situation was handled well. Laser Tex took action which prevented him from becoming a victim and allowed everyone to walk away from the incident unharmed. That's a good outcome.
