Actually from looking at several videos of the incident, it looks like the security guard (who appears to be Trump head of security) took a sign which was leaning up against a concrete planter and the guy that assaulted the security guard wasn’t even near the sign when it was taken.
Don’t let facts get in the way of the troll who is very concerned about the “rights” of the latino who got “sucker punched” and had his “property” “stolen.”
