Popular today among the people who couldn’t figure out how to google if it were the only ransom required to save their own mother: “already over 800,000 bikers on the road to confront 1 million Muslims in Washington.”
Actually, the photo was taken by Tech. Sgt. Cherie Thurlby, USAF in 2005, as part of an event called Rolling Thunder (official site) that is repeated annually since 1998 to recognize fallen soldiers from Vietnam and missing soldiers from all conflicts. You can see it being used in this Military.com article and this DoDLive.mil article dating to 2005 and takes place in one of the the Pentagon’s parking lots.
But there’s more to it..
The photo also appears in a lot of other misattributed biker-protest articles like this one as if it were part of a 2013 event, so it looks like it’s just used as a “proof” photo so someone can just make up something about bikers to get excited about, but not even be real.
While the 2013 “2 million Bikers” event does appear to be partly true (mostly, according to this and this, at least), the photo shown is not part of it, nor were there even a “million Muslims” to ride out to confront.
The “million Muslims” actually only had a turnout of “a few dozen” (per wiki) and even the Council for American-Islam Relations (CAIR) refused to endorse it despite being reported to have been invited to help plan it — so even the idea that the bikers would ride there to “confront 1 million Muslims” isn’t even real, either. Looks like someone is either trying to fool a lot of bikers by using that photo, or thinks bikers don’t don’t have enough sense to make sure what they’re riding thousands of miles for is even real.
