First of all, in every case I stated that the shoplifter got busted in the parking lot or getting into their car. Last time I checked you couldn't park your car inside Wal-Mart. Second of all, undercover security can and does lay fingers on plenty of people, and when they need help they can get assistance from managers and cart boys alike. Shyt happens all the time.
Undercover security will stop you and ask you directly or indirectly if you have stolen something after you have left the store if they strongly suspect you of stealing but didn't actually see you at the moment you stuffed something or if another employee has seen you stealing. In that case they will just be basically issuing you a warning or if are stupid enough to confess they will try to take you inside. But if they actually see you stealing stuff they can and will try to physically detain you if you resist their version of a citizen's arrest. The undercover security NEVER let anyone go if he saw them stealing, at least when I was there. That was the best part of his job, taking people down. He didn't have anything to worry about, he was cool with the cops anyways.
I'm not saying that there was a physical confrontation with shoplifters every week but it happened enough where it wasn't anything shocking. Wal-Mart actually had a little detainment cell right across from the accounting office and you could regularly hear people crying, screaming, and cursing from there. Once in a while you could hear or see people getting up from their chairs and being pushed back down by security until the cops got there. Our undercover security was a badass, he had one of the highest conviction rates in the state. They used to bring in other undercover security officers from other stores just to train with him. He was this big older mexican guy with an OG mustache and tattoos everywhere, the last guy a shoplifter would expect to be security. But the guy ended up getting fired for guess what? Stealing from the store.
I can't believe you guys think my stories are BS. You do know that Wal-Mart security and cart boys have literally KILLED shoplifters in the parking lot right???
Maybe things have changed in the last few years, but shoplifters were still getting messed up if they fought back when I was there.
