Not only who is funding etc, but someone must be sending out emails and talking points. Like carry US flags, not Mexican.. There has to be electronic or written info out there. Someone needs to find this info.
Every major city has a large Latin-American Association that is very left wing. I've been to a few meetings here in Atlanta few years ago and they had a very Amnesty International-type vibe. I have no doubt that they are behind much of the organization of the rallies.
The flag thing was a no-brianer. They watch TV and saw how badly it made them look. The white t-shirt idea was a no-brainer as well.
I heard somewhere today that Spanish radio was passing the messages about the flags because the mexican flags were causing a backlash.
I have video of the keepers at the San Diego Rally.
