Things Got Crazy On Grant and Stone In Tucson

I was headed to dinner tonight. Driving through Tucson I had just come off I-10 East bound and made a right onto Grant. When I got to Stone I noticed cops were every where, helicopters above so I did what anyone would do, I logged onto twitter to find out what happened. I discovered there had been shots fired at a patrol vehicle after a short car chase. One man had fled the scene which is why the helicopters were flying above.
