This is nothing new to her. Cheerleading squads have always had a strict code to follow. Same as the Miss America contests, while they model swimsuits they can't be vulgar in their attire such as skin tight tee's and micro mini shorts. She knew what she was doing and she should have been canned.
Question: Could she be kicked off for wearing a string bikini at the lake?
How about going to the mall w/o underwear with low rider jeans on?
How about if she were a waitress at a restaurant that served alcohol?
How about if she worked in a bookstore that sold Playboy?
