That's some heavy duty addiction.
3 million British pounds is approximately 5.3 million dollars .....a week! Every week. TO be honest with you I do not see why they would continue doing this ......I would (were I a criminal) personally 'work' for maybe 2 months, and then give the entire biz to someone else (I wouldn't even want to keep any ties to the setup). Too much risk trying to keep this baby moving forward perpetually, however a couple of weeks of hard 'work' could have nigh anyone well set for life. Let others be worried about staying ahead of the cops. I'd find a nice tropical place (without extradition treaties of course) and live well on coconut juice and exotic women with names that are impossible to pronounce.
