Filmed by an attendee of this past weekend's 50th Annual Puerto Rican Day Parade in Philadelphia, the footage above shows a pretty clear-cut case of police brutality involving what appears to be a woman discharging a bit of silly string in the direction of some cops, and the extreme overreaction of a white-shirted officer who busts her up with a sucker punch.

Gisela Valentin, who recorded the scene, claims the white shirt was responding to the actions of another parade-goer who can be seen around the two-second mark spraying the policemen with a few drops of water.

There is some debate over this, as well as over what precisely the assaulted woman was doing as the clip commences (she can be see brandishing an object on the far left), but it's fairly evident that neither her actions nor those of "water bottle guy" warrant the use of excessive force, especially by a high-ranking officer who is supposed to be setting an example for the rest of his department.
