Apparently idiots, criminals, and idiotic criminals are going all-out nationwide with this Clown silliness.
What started as just creepy and seemed to be mainly induced hysteria from a few examples is rapidly ending up criminal and the Detroit area is not immune from the sending in of the clowns:
The Detroit News: Cops: Armed man in clown, pumpkin mask robs hotels
The Detroit News: Detroit area clown encounters play into fears nationwide
Somebody is likely going to get seriously hurt if people dressed as clowns keep assaulting people, and it will likely be someone wearing clown shoes.
