With heavy snow falling along the eastern seaboard a call went out for a big snowball fight at 4th and U. in Washington, D.C. A man showed up and started waving a gun around, apparently after his SUV had been pelted with snowballs. The crowd started chanting “Don’t bring a gun to a snowball fight.” The man with the gun turned out to be an off duty police officer who can be seen talking to someone over a walkie-talkie. Apparently he was calling for backup as uniformed police began arriving at the scene of the…what? Man with gun vs. kids with snowballs? The off duty cop who was waving his firearm around has reportedly been assigned to desk duty while the police department tries to sort it all out.
