Which law did Grayson break?
Per the article, I can imagine: Trespassing (which is why he was forcibly removed). Terroristic threats. He participating in intimidating customers which makes him a fun candidate for inciting violence. Heck, how about some of those fun bullying laws. Disorderly conduct. Organizing without a permit. Probably drunk in public based on his personal record.
He’s a complete dick so that makes him guilty of exposing himself to children. Assuming there were children at Wal-Mart that day.
Man, take your pick.
