Good luck in most instances. I know that for the Philly event, if any nitwit tries this at Independence Hall, the Park Rangers will be all over them. I imagine cops will do the same elsewhere.
He also stated he knew what kind of trouble THAT would cause (riot anyone?). He then told us if anyone came over and caused trouble, don't take it upon ourselves, just go and tell an officer.
Well.....a man came over and stood w/ us with his 2-3 year old daughter on his shoulders. He started yelling anti-American crapola. We of course did not say a word (his little one was an innocent he used as a shield) so I went over to the 3 officers that were on our corner and told them what was happening.
They removed him immediately (kindly of course).
