Security cameras weren't around while Betsy Ross was alive and sewing flags. Neither was frozen food. And the alleged perp: He wore sneakers.

This crime might have been the most historically inaccurate crime ever committed at a Colonial-era site.  

Security cameras show a man stealing frozen food overnight from a food stand at the Betsy Ross House early Wednesday morning. The cameras depict the man walking toward a fence with two (historically inaccurate) boxes of frozen food. He stashes them near a fence, grabs a bucket, then hops the fence and leaves the property. 

No word on whether he was riding a horse.
