Agreed.
She may have “hit” the barricade while attempting to turn around.
Exchanged words with a bunch of very nervous cops.
They drew their guns, a shot may have been fired, by a cop, oopps, and she rightfully freaked out and speed off.
I think this is pretty close. First round fired was probably a ND. The cops in DC are jumpy these days. Once one round goes off it's likely to become an all-hands mag dump.
I know this. You don't ever want to be around a cop who draws his firearm. The trigger finger discipline or, rather, the lack thereof, is truly frightening. And, pace lady FReepers, the women cops I've seen are the absolute worst.
