This is OccupyFreedomLA's livestream covering the National Gathering in Philadelphia this July 4th evening, and it seemed like a great march, but as of 9:50pm EST they are surrounded by police and not being permitted to move. Oy.
No exact count on number of police present now, but best estimate is hundreds of them. They have blockaded the marchers in a plaza, and are armed with batons and flexi-cuffs and for whatever reason they look prepared to start arresting people again. It was clearly a peaceful march.
Several livestreams have gone blank in the past minute or so, it's 10:06pm EST, so here is an alternative stream that is still running, in case OccupyFreedomLA gets cut off as well:

It's 10:12pm EST and according to Twitter #NATGAT, the first arrest of the night. Many tweets say marchers are not being allowed in Love Park do to a shooting earlier today. I don't know if this is accurate, or any details of any shooting at this time.
