Two and four legged predators have become a serious threat to the people of DC. No doubt the black bear was innocently looking for a quick snack, like a jogger or unattended stroller or something, while the scumbag is looking for self gratification at the expense of his victims. Both nuisances could be remedied swiftly by a responsible individual using a modern self defense tool, but such things are not permitted to the citizens. Until they are, it looks like personal safety of DCians is in the super capable hands of the uniformed division.
I wouldn't get my hopes up.
