Sounds like you have a hard time believing that the US gov't might be involved in anything "below board"...
The "war on drugs" gives the feds a large leverage on tax spending. Gov't likes being big and important. A new alphabet agency is like a blank checkbook, with an awesome retirement scheme. Not saying we don't need these agencies, and not saying that all involved are crooks, but corruption is universal. Do you think all of the hired help (politicians and bureaucrats) are always 100% in the right and doing all they can to be honest and truthful?
I can't be bothered to look it up, but wasn't there a Tom Cruise movie in the last 5yrs or so where he was a pilot that was recruited by the CIA or ? to run drugs or money? Pretty sure that was based on a true story. And crack was supposedly imported into the inner cities to widen the race gap, not sure about that one but I have heard it. Might be an urban legend? Would not surprise me either way. Drugs are big money, I read a thing that Kennedy was "removed from office" by the mob due to his increased pressure on organized crime, even after the mob was supposedly instrumental in him winning in certain areas. Then Johnson throttled back on that pressure after he took office... Food for thought. Will we even know the real truth, probably not. Just follow the money, and drugs produce a lot of money. Not just for the guy running the cartel...
I do believe members of our government has been involved in some nefarious activities. But when somebody makes an outlandish statement about the government, you need to be able to back it up with facts, not just hot air and BS. And I don't draw my facts or conclusions from some movie I saw @ the theater or on cable tv. That's just plain stupid. I read and research.
