How ISIS gets its money and where it goes

CNN had a excellent "short" on how and where ISIS gets its money. Extortion, kidnapping, theft, arms trading, slavery, you name it, they've mafia'd it. And although I didn't hear much about ISIS (ISIL, IS) until last summer, this is a vast, well run money organization that didn't develop over night, and how did our President call them JV? They seem better organized than a lot of our state and local entities
