Transferrred to OT as this could npo longer be considered related to PIC's Sawn Off shotgun in the boot (trunk) pointing into the passenger compartment and triggered by the alarm system (obviously with suitable delays etc for maximum effectiveness). Not my idea I just remember it from a newspaper report of a court case somewhere in the USA. Couple of other ideas at http://www.autotaser.com/Products/AUTOTSR.htm Of course being in the UK I could possibly suggest that either of the above could be condoned as they are illegal. And any other device you can think of which may inhibit or deter a Property Liberation Operative from going about their business will probably result in you being prosecuted under Health and Safety at Work Regulations. :-( Chris -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
