I have run Itinerant gangs off in the past ,, once in 1981 with a bluff by covering the headmans car and caravan with petrol and lighting a cigar ,, also asked them to pay damages ,, they had a discussion , couldnt decide whether I was barmy , suicidal or bluffing so they paid up and all left ... Next day cops visited me , confused as to why a 9 vans and almost 30 Itinerants had suddenly driven from Crawley to Bedford As fast as possible ,,, i said i knew nuthing and they left it at that as no one hurt and the Itinerants were gone which the cops were pleased about.. another time in 1993 The Factory carpark in Purley where i worked was invaded by 24 Itinerant vans overnight and they were shitting everywhere , dogs amok , our cars getting damaged , theiving ,The cops and council told managers that it would take court order and 3 weeks to remove them... I set up a SATCOM transmitter on the loading dock aimed at headmans van. with it switched on and pulsing but not actually transmitting the deadly microwaves that would have cooked them alive ,, but when one of the cheeky blighter s asked me what it was, I told him that whoever was in that caravan would be sterile in 12 hours dead in 3 days . The whole mob moved on in 2 hours ,, had to explain to the cops that it was not transmitting , and everyone was happy especially the management , even got a pay rise 2 weeks later .
