I had a situation at K-Mart recently. My wife had bought a big bottle of aspirin from another store, and they didn't deactivate the security tag. She kept it in her purse, and it set off the door alarm at K-Mart. The lady asked to see her receipt and searched her bag. When nothing was found that would set the alarm off, she asked my wife if she had anything in her purse. My wife cooperated and it was determined it was the bottle of aspirin and that was that.
So my question is, had my wife said that they couldn't look in her purse, would they have had probable cause to detain her? Also, do they have the legal right to check your receipt and bags? Thanks
