I know that most of us feel the same way about a single cell organism that goes around running over cars but the sad fact of the matter is that the police have little or no interest in apprehending such people but prefer to just ask you if you want a crime reference number for your insurance.
The delicious Irony in this is that had any of us had the temerity to grab them and give them what they deserve the up to now disinterested members of the local constabulary would rise up and bring down the full force of the law down on your shoulders. Seems that the police are at best ambivalent about vehicle vandalism but are ready and able to act on the vandals behalf.
