Just a heads up. We may have to deal with anarchist elements hell bent on causing trouble.
From Indepundant:
Sounds like the black block or something similar. They have no agenda except to instigate violence with the cops and anyone else around.
THEY COME PREPARED TO DO BATTLE and they are well organized.
Seriously, it's not just bandanas over the faces, they have BMX or hockey pads and protection on under their clothes, they bring improvised weapons like D-Cell batteries in socks, flammable liquids in unmarked water bottles, etc.; stuff that can be quickly assembled or disassembled into innocent components carried by multiple persons.
If their target is the Memorial, they will likely create a diversion to get the police away from the Memorial. If they want the Gathering of Eagles folks away, they will create a physical confrontation with them in one area, hoping to draw the rest over and then they'll hit the unprotected area. If you're protecting an area, stay at that area. When your adrenalin gets going, you'll want to go help, DON'T DO IT. The Eagles need to have people free from protection assignments to respond to these diversions so the Memorial is not left unprotected.
They use cell phones, hand radios, police scanners to keep their people informed. They will have folks on bikes or skates so they can move quickly from one spot to another (unprotected) spot.
Oh and most important: As tempting as it will be, do not let the black block folks draw you into any violence. Philosophically, you don't need to lower yourself to their level. Practically of course you can defend yourself, but be forwarned that the black blockers will turn that around on you too.
They will have people whose only job is to get photos and video. Any pics or vids of you defending yourself will never see the light of day. Any pic or video that can be construed as you initiating violence or "over" defending yourself will be on the media and attached to a criminal complaint, a lawsuit, etc.
Because of this it is important for the Eagles folks to have assigned pic and video people too. The black blockers will injure themselves and blame it on you. They will start s--t with you and only film you responding. They have lots of free time to edit their videos and pics then distribute them to anyone who will look.
The DC cops, Capitol Police, and Parks Police already know all this from experience.
I'm on the other side of the country and can't be there. Please pass this info on to the Gathering of Eagles folks. The more prepared they are, the less chance of success from anarchists. It's important they don't succeed because if they do it just emboldens them to stoop even lower for their next "action."
