Vandalism plain and simple.
Most likely a drunk U of M student (spoiled brat who never had to pay for anything in his life) pretending to be bada$$ by stabbing car tires.
A car down the street had it's windshield busted in last week. Who breaks a windshield but a vandal? I mean; to break into the car you take out a side window, right?
I'm sure the
IMPEACH BUSH sign on my lawn had nothing to do with it. However if you guys are desperate to give Bush credit for something, be my guest.
