Your probably better off "busting" him on yer own. The legal system won't give you the kind of justice your looking for. I mean,it'd be like a crack head complaining about his supplier charging him for bunk stuff,no sympathy from the cops on that one either.
If you did sucessfully roll over on a sourse that fucked you,who knows who else might be in his data base that the cops would now have access to. So potentially you coulds fuck part of the legit food chain.
Just my 2c Elmo,but I'd take care of it myself if I needed to.
