Yeah this happened to me, my house got shot up and a bullet whizzed over my desk (where I would have been if I was at my computer) and into the wall over my sleeping head.

The police response was basically "well, sometimes people do this, but they usually don't hit anybody LOL". I didn't expect a full-on CSI investigation but really, my girlfriend or I could have died, I wanted something. There were never any charges, and I'm pretty sure there was no investigation beyond writing the report. It was really disappointing and disillusioning.
