Walmart says it's testing body cameras on some store employees

Walmart said it's testing body cameras on some store employees, a move that comes after some of its locations have experienced shootings and other violent incidents. 

A Walmart associate checking receipts in a store in Denton, Texas, was spotted wearing a recording device earlier this month, according to CNBC, which cited a photo shared by a shopper. Walmart on Tuesday confirmed with CBS MoneyWatch that it is piloting the use of body cameras. 

"While we don't talk about the specifics of our security measures, we are always looking at new and innovative technology used across the retail industry. This is a pilot we are testing in one market, and we will evaluate the results before making any longer-term decisions," a Walmart spokesperson told CBS MoneyWatch.
