By the time we made it to 4th street, the protests appeared to have passed. So far we have yet to witness any protests get out of hand and the massive assembly of law enforcement officers has kept things under control.
The security perimeter around convention facilities almost forms a mini city, secured by a Trump-worth wall. Border security around here is excellent.
There have only been two protestors within the arena who had smuggled in contraband signs. They were quickly escorted out with few evening noticing.
