Collin Rosenmarkle's Dad Couldn't be Reached for Comment

Collin Rosenmarkle of Burke, Va. , burns a $20 bill as protestors,
who are calling for an end to the Federal Reserve and are part of
the Occupy D.C. movement, demonstrate in front of the Federal
Reserve, in Washington, Sunday, Oct. 9, 2011.

Can't be for sure, but if he'd earned the twenty himself, ("you want fries with that?") I doubt he'd be so quick to burn it.
