A fraternity brother of mine is a special investigator for the IRS, he has some stories that will curl your toenails. Big dope dealers always launder their money, hense the IRS is involved. The DEA and his task force do raids together, they get hundreds of lbs of coke and shit. He sends me news paper clippings of his work, some takes literally years to put together, gets multi-millions in houses, bussiness, cars, etc.
Needless to say, the people he deals with aren't street level, they're the real deal....
