When Jake Guzak visited Capone in florida after his release he told people he was pretty much shocked at how bad Capone looked.

Then he said Capone was "Nuttier then a fruitcake". Maybe they acted like Capone was still the boss when they were with him but personally i doubt he was running anything at that point, though i could be completely wrong on it.

After his release Capone was probably lucky if he could tie his own shoe laces.

Just my opinion, i really don't know what the real facts were.
