TMAC,
It funny that a 10yr old can see what's going on in plain sight and the authorities can't.
In Manchester there is a great collection of sellers of all things from T-shirts,handbags, perfumes,watches anything that has a designers label can be found there, some provide better counterfeit products than others, everyone knows and occasionally the police HMRC and UK border agency visit.
This simply disrupts the sellers but they are up and running again within 24hrs.
The only thing I ever remember was when there fireworks guy got busted and ironically he was a legitimate company no doubt the book was thrown at him.
Regards
premier
