Ouch!

Ugly wreck (picture from WBBM780):

Officer should be OK though:

• A Chicago Police officer was hospitalized in good condition early Tuesday when his squad car slammed into a building on the city's West Side.
  
  The squad car -- which was not on its way to an emergency call -- was eastbound on Madison Street around 2:40 a.m. when a car that had been parked started moving and pulled out in front of him in the 2500 block of West Madison Street...

We're assuming he was working 99? Because anyone in the passenger seat would have been destroyed along with the squad car.
