Let's assume 100 people were around the incident and immediately formed when it occurred - and 100 or more came from your side and 100 or more were coming from the other side and all jammed up - and you couldn't move into this mess - how was Disney supposed to get into the mess and get it cleared more so than than they already did?
They have 20 security officers and 5-15 law enforcement agents at every checkpoint probing every inch of our diaper bag and you wonder how they could be any faster at clearing two idiots fighting on a walkway?
Drag idiots away, direct traffic as stated in previous posts. Pretty cut and dry.
