People do strange things when they’re caught being stupid.
When the store’s loss prevention staff accused her of theft and pulling her clothes partway off didn’t convince them otherwise, she resorted to violence. According to police, she hit one of the employees trying to detain her in the face, then bit his arm. She left “visible injuries” in the attack, but nothing bad enough that the employee needed medical attention.
Dumb people do even dumber things when they get caught. I’ve seen tweakers around this area do similar things, but not quite that grotesque.
