Calling these guys smart is like calling them good businessmen.

It's easy to pull things off when the first drawer in your toolbox has a tool named murder and the second drawer has terrorism, and so on and so forth. And even then they still manage to fuck it up half the time. And if the Feds would have paid better attention to the wiretaps they'd have had him way earlier. He still died in prison.

Smart? I respectfully disagree.
Less of a Dumbfuck than most of the other Dumbfucks? I'll go along with that.

You need a yardstick to measure distance, not a weight scale. And vice versa. He spent his life in and out of prison and with the threat of imprisonment over his head. His greatest "accomplishment" in life is that he was head of a ruthless, murderous crime organization for a long time, only because he created his own prison in faking mental insanity over three decades. He was a piece of shit for his entire life. And if he was smart, he sure found an amazing way to spend 50 or 60 years wasting those smarts.
