Rats Backlash

There now seems to be a rats backlash in New York City after video and photo of a rats infested Taco Bell/KFC restaurant hit big time on the web. Restaurant owners are complaining that they are unfairly targeted by the Health Department. None of them are actually denying that their restaurants have rats. They are saying they are now being tickets for conditions that existed before that they were ticketed for. I wonder what makes them think that it is OK to have rats in their restaurants.
