For the third summer in a row now my in laws have had drunk teenagers roll out the local park between 12-5 am and then walk down there road pulling the mirrors off all the cars. Last summer they did set the dog on one of them but he got nasty so they don't want to do that again. Got them on film but the police have said unless you have names and addresses we can't do anything? I have offered to camp out with my baseball bat but I guess it will be me who gets in trouble for doing them. Only plan I can think of is blue tack drawing pins under the mirrors to mess there hands up and then get rid of the evidence? Or just rant at the police because at the end of the day there tax payers and if the car has no mirrors it's them that get in trouble or have a mot fail. 10 mirrors in this time they've had and the neighbours are sick of it.
