"Most widespread political action" 

My bud Ratel added this little piece of trivia.  Is there a list of previous political actions that would indicate that this is the case?  Wouldn't the political agitating in Mosques or highly-centralized churches (Catholic, etc.) be larger?  And don't those things happen every week?  And where does this 5200 number come from?  The 350.org organizers?  Did anyone take the Tea Party or 9/12 or MMM people at their words for headcounts?

Not verifiable.
