Disgusting. We had a spate of that crappola right here in my little town recently. I don't think it is still going on though.
About two dozen houses were hit.
One old timer in a wheelchair two streets over from me had his flags torn down and ripped to pieces. The American flag and and Army flag. He's a WWII vet (I don't know if that's why he is in a wheelchair). My wife works with his granddaughter, her and her husband live with him. She says he was in tears when he saw his flags out on the lawn like that.

If punks like this are ever caught I'm guessing it results in a mere slap on the wrist. I don't think that's enough. I don't care if precious little Johnny is a saint and has never been in trouble before. This sort of thing rates a higher level of response from the courts, considering the emotional damage done to an 85 year old, not to mention this is our flag.
It's not like there were some rose bushes or petunias torn up, minor property damage, this is something quite more serious.
