The video belies the theory police were getting shoes for hurricane victims. A reporter asks what police are doing. The response from an officer is 'looking for looters' (as patrons and officers wheel shopping carts full of goodies behind her). The officer never mentions getting shoes for the hurricane victims. In fact, the response to the question is rather nonplussed.
So the cop, who undoubtedly had lost his home and all his possessions in the flood gave a snotty reporter a sarcastic answer ~ the reporter is fortunate he was not arrested and hogtied for interfering with whatever it was the cops were doing.
