To Catch a Thief, Part 1

S6, E25: When jewelry is found scattered on the floor, Les think it's just a mistake. But when it happens again - and the security video system conveniently goes down - he knows something is afoot. The Golds set up a plot to catch the culprit, but will they be outsmarted once again? And, when an unruly customer threatens Les on his home turf, the situation becomes more than his security can handle - and they must turn to the Detroit P.D. Plus, a pair of sneakers worn by Shaquille O'Neal take up a lot of space on the sports shelf - will Seth be able to find a buyer?
