After the University of Arizona lost to Wisconsin in the NCAA Division I Men's Basketball Tournament on Saturday night, Arizona students took to the streets in Tucson, Ariz.

Riot police had to be called in to control the situation. A video posted to YouTube showed what appeared to be one of the riot cops using excessive force when dealing with a young woman.

The woman simply appears to be walking along when, out of nowhere, an officer blindsides her, knocking her down and causing her to be hi-low'd by a bench she was walking past.

Within the context of the video, it does not appear as though she was doing anything wrong or causing an issue. It looks as though she was just walking by.

We're assuming that this is going to become a bit of an issue for this officer rather quickly.
