Correction: These billion dollar companies don't "pay" to train their security people in the use of force. It's all about money/liability. They don't give a rip about sending some person out there to play security who has near zero training and are totally unarmed. If they only want an observer, just install cameras in the store and parking lot if they don't have them already.
I think we are saying the same thing. I can add in Mervyns, Big Lots, and target in my daughters employers (she’s at Disney now) they were told to not get physical, bit some of the employees do.
