I'm surprised so many here are reluctant to walk out of the store.
Of course Wal-Mart or whoever doesn't violate your constitutional rights by trying to stop you, searching your bags, or grabbing you, or even beating the crap out of you. But so what? That's not the end of the issue. Someone who grabs you on the street, looks through your bag without your permission, or just detains you with a threat commits a crime even if he doesn't violate your constitutional rights.
Wal-Mart's employees are subject to the law just like everyone else. If they are going to lay hands on you, they had better have a good reason. There's no law against walking out of a store. And Wal-Mart can't threaten you or use force to detain you against your will just because they drew up some sign for their window concering their "rights" to search your bags. Their blue vests and name tags don't give them any special powers. Suppose you put a sign up in your window: "Owner reserves the right to threaten or physically coerce all who enter". Good luck getting out of an assuault and battery charge when you exercise this "right" on someone in your house-- and that sign's a lot more explicit than some sentence about rights to search your bags.
So, if Wal-Mart or whoever is going to stop you, they need a good reason, like a suspicion of theft. They need a good case for thinking that you're committing a crime, in other words-- just as you would if you grabbed some guy on the sidewalk.
It's not just a criminal matter, either. If someone is detained and inured, the store faces stiff civil liability unless they can justify the actions of their employees.
And, whatever some of you think, that the dumb machine up front went off ain't gonna cut it as a reason to threaten or attack a citizen. You wouldn't have to call an electrical engineer to the stand to remind a jury that those machines go off all of the time without anyone stealing a thing. They go off when the sales chick doesn't deactivate the whatever-it-is, they go off when you buy something in the sporting goods department and they forget to clip the tag, they go off for who-knows-what reason.
But don't just take my word for it. Retailers all know this good and well, too. That's why they'd be off of their rocker to do anything other than instruct their employees to leave you be unless they
see you conceal some item and then walk out of the store with it. And that's exactly their policy, unless they're nuts.
Several times that machine made noise at me at Wal-Mart. I don't steal. But I didn't want to stop and be searched just because Wal-Mart's equipment doesn't work right. So, I just kept going. The old guy in the front of Wal-Mart came out a couple of times after me. I was friendly with him-- I've got no beef with him-- but I said that I didn't take anything and the machine was just wrong and that I hoped he had a good day. I smiled as I said it, but I didn't stop.
Anyone here think these circumstances would justfy threats or even violence to detain me until the cops arrive?
If you said, "no", good job! You win the good legal sense award for the day. If you said, "yes" and you do retail work, don't let your resume become dated, and keep your lawyer's card handy.
