They can for a short period of time. But they would have to make a bust immediately after the receiver got the product. They couldn't just start vending here long term in some bigger play to hit SR. Not happening. They can't just start introducing narcotics into circulation long term. Iran contra and the Afghan/Soviet war dope debacles were a different story. That was intelligence agencies and international military backed covert operations. The CIA is not going to start vending coke and molly and pot on SR. If the DEA/FBI/local le does it, it will be VERY controlled. Imagine if they started introducing kilos of heroin and coke and meth into the streets and somebody blew the whistle. Would make the Fast & Furious gunrunning look like a walk in the park.
