This is frightening: http://www.desmoinesregister.com/story/news/local/2015/12/11/police-grandma-wore-fake-beard-get-into-city-high/77166044/
Fortunately the school / police did something, but really this person should be in jail for this behavior. Just think, if this was some random person they would be in jail (or shot and killed) right now for their actions but because it's the 'grandmother' they're being awfully lenient. We don't live in a society where you can get at children like that. Sick sick sick! At the very least she should be on ankle-bracelet monitoring so she can't go in the school.
