I know hoe you feel, we caught some junior thugs cutting the fuel line on a neighbours car on Friday and then found out that they'd been at this kind of thing for a period of 2 weeks in our street,then on Sunday night they broke into my car, and the same neighbour's on Saturday, the fire service had to come out to wash all the leaked petrol away, which is probably what finally shamed the police into calling round. But we all know nothing will be done and any threatening behaviour on our part will only escalate the whole thing. I get so pissed off and am out checking the cars at 6 am, when I should still be asleep!
