Oreos make surprisingly good projectile weapons. Not lethal, of course, but it’s as good as a beanbag shotgun for crowd control. The rioter you hit will get an owie, and the rest of the crowd will stop to eat the Oreo, thus ending any street melee situation.

Of course the Geneva Convention expressly forbids using Twinkies in crowd control weapons. I can’t remember if it’s mentioned under germ warfare or biological agents. 

(Thanks to Gerard at American Digest for sending that one along. You can always find him in the front ranks of any mob actions where Oreo crowd control weapons might be deployed. With his mouth open)
