I tried to find a video that matched that description but was unable to. I have never been trespassed, though I had been in the past harassed by door greeters, and loss prevention(Walmart wannabe cops). I voiced my concern to corporate, and they have given their store managers the green light to "escalate" non compliance of receipt checking(using force).
This is unacceptable for my wife, and myself, we will no longer shop with them. Not sure what has changed their attitude but every body who values honest people being treated with respect should boycott Walmart. My final straw is when I saw a elderly black lady stopped at the Camaron Walmart on 87. She had a cart full of groceries, and they forcibly scanned every single item, and found NO unpaid for items. The lady was furious, all the employees should have been charged with kidnapping. But due to a loop in the law allowing store personal(civilians) to detain suspected shoplifters, but they must have probable cause. Walmart managers, and LP are claiming purchasing items, and not showing receipt or refusing scans is probable cause. Hopefully it ends up in court, and they are taught a lesson.
