Maybe the Zero Halliburton people could include a free, bright yellow label for the outside of the bag that reads: "HIGH VALUE LAPTOP COMPUTER INSIDE. DO NOT STEAL". Of course the bags will have to either be unlocked or have TSA locks.
I feel sorry for the poor folks trapped into having to go through UK airports this week. I'd have taken the train/ferry and come home from DUB; CDG; BRU; FRA or anywhere that I wouldn't have had to check my laptop.
