For a little context, ICNA is not a particularly nice bunch of folks, they're accused, rather credibly, of having ties to Hamas, the Muslim Brotherhood, etc. Five of their members got picked up in Pakistan last year, and two of the speakers at the event were Imam Siraj Wahhaj and Amir Abdel Malik Ali, Wahhaj is usually listed as an unindicted co-conspirator in the 1993 World Trade Center bombing, and of course Abdel Malik Ali is perhaps best known for his comment “Palestinian mothers are supporting their children who are suicide bombers, saying, ‘Go honey, go!’ That ain’t suicide; that’s martyrdom.”, both are also former NAtion of Islam members. ICNA, on the other hand, once refused to let a vice-mayor greet their organization because they worried about her voice being sexually seductive, and so some might view them raising funds to help women with a bit of skepticism. I of course make no judgment myself, but one could see how a Rabbi, one of the people prominently listed as an organize in the video, might perhaps have doubts about the friendly and peaceful nature of an organization charged with terrorist ties who invites speakers who are best known for their alleged involvement in terrorist attacks and open support suicide bombers.

I am, of course, sure that this merely slipped the mind of everyone who reported on this, a number of news outlets did not, who also seem not too have mentioned that this was a rather large protest of several hundred of whom a small number broke off to act crudely, and there actions were condemned after the event by its organizers. The rabbi whose name is mentioned when asked on this said, “I participated in a peaceful protest on the lawn a hundred yards away from the Yorba Linda Community Center. The Mayor, city council members, congressman, the local reform rabbi, and others spoke. Another demonstration started near the entrance of the Community Center. Those in the second rally spoke harshly as indicated on the video. We did not join them, in fact we told people not to go there.” And said the video was heavily distorted.

Which NBC also pointed out, “…video of protesters hurling insults at the Muslims were shot in darkness, apparently several hours after a sun-splashed afternoon rally…”

None of which changes that there were definitely people acting rather poorly, to say the least, on that video, but it does appear to be something of a propaganda piece and it seems to be being distributed as such. Nevertheless, bad behavior by some of those protesters, but not exactly the black and white it's presented as.
