First off: WELL DONE CHRIS!
Second: I'm shocked the usual gang of suspects that take the following position haven't been out in force on this one.
I'm not going to fault you for doing the right thing. You stood up for someone. Just be aware that things like that may, in the future, end up with you drawing down on someone. Is it worth it? Remember that the thieves, while scumbags, are people too. I'm going to say you did the right thing, but it's not something I would have done.
Maybe it's cowardly, but I don't want to waste two people over a trifling confrontation about 1.50USD worth of cookies, however wrong they may be.
Usually anytime someone hints at or actually participates in a situation like this, that may or may not even involve a gun, we get a chorus of some of the following:
-You should not have been in that position in the first place.
-Perhaps you should have not left your home that morning.
-Keep your mouth shut and just call 911.
-Keep your mouth shut, it is the company and cashiers problem, not yours.
-The $1.50 for the cookies isn't worth a fight, brandishing, or shooting. (But they can never answer what price would justify that).
-You should have had the 6th sense of awareness so that you would have known long before you even got into the Quizno's that there might be a couple of bad characters in their trying to steal, and thus you could become involved.
-You should have employed some form of verbal judo, de-escalation, or jedi mind trick to avoid them even becoming confrontational and waiting at your vehicle.
-You shouldn't have even gone out of the store, you should have run out the back or called the police while sitting in a corner remaining calm.
Obviously some of this is tongue in cheek, but a lot of it is the norm of what we read in Strategy and Tactics at times.
To the OP I think you did great. Thank you for standing up for what is right and being willing to say something and do something about it. If we had a few more people that cared in this country and world, perhaps it would be a better, safer, more humane place.
You weren't a wanna be cop, you weren't a mall ninja, you weren't a vigilante out on the prowl, you simply were a concerned citizen that did the right thing. Let me finish by saying, if criminals did not put themselves in a position where they were stealing, assaulting, robbing, murdering, raping, burglarizing, vandalizing, etc... They probably wouldn't even be in a position where they could be shot or injured. Why don't we start putting the blame and responsibility on the criminals instead of the law abiding that stand up to them?
As I began, GOOD JOB!
