“My plea for everyone watching this, not just for the day of the game, but ahead of time; if something seems out of place, if something is unusual, if it doesn’t fit with the narrative of what you’ve seen, you’ve got to let somebody know,” said Jesse Baker with the U.S. Secret Service.

Parade-goers were reminded that they can bring chairs but no couches or pets. Only small barbecues that are less than a foot-tall are allowed.
