Local couple cries foul at Wal-Mart after they'd shopped, selected, purchased and paid for some stuff. They had exited the store with their things when three Wal-Mart employees and a plain clothes security guard blocked them.
They had to submit to being searched despite having receipts for everything they had. After finding no stolen merch on them, they let them go.
But still, you're going to do something as brazen as this without any hard proof? I'd make for damned sure to make a HUGE scene if someone wrongly accused me of stealing from them. And then I'd for damned sure sue the store, the Loss Prevention agent and anyone else I could.
