Yes, complaining with an axe in your hand and wearing a balaclava, or driving a stolen fire engine through the hangar doors is a bit extreme, but I guess they got the result they were after.
The units I worked at had security surveys done after that and the other incidents, i remember the idea of a high fence around the pad and hangar was costed at around £85K, so it was binned and it was decided we'd put it away after every job as that didn't cost anything.....apart from the resulting increase in response times.
