I agree with racedo: a bit here, a bit there never hurt anybody. People get caught when they get greedy. First time maybe they managed a to get a carton of 200 in. Once they've finessed that the next stop is a master carton of 10,000. After confirming an outlet for more goods it's a 40' container with 8,000,000 in.
These guys got greedy and no doubt if they weren't stopped the bad guys they were selling to would have upped the game and started asking for something a little more valuable and a little less bulky. We've all seen the film Layer Cake, once you're in the only way out is in a box.
After these idiots have been sent down the Proceeds Of Crime Act should kick in and empty their bank accounts, drag their kids out of fee paying schools, strip the fancy clothes off their wives backs and repo their cars.
