Capone and His Taxes
Capone never filed an income tax return, owned nothing in his own name, and never made a declaration of assets or income.

Capone in Alcatraz
Because word spread that Capone had taken over in the federal prison in Atlanta, he was sent to Alcatraz. There were no other "outfit" members in Alcatraz, and security was so tight that he had no knowledge of the outside world. He was unable to control anyone or anything and could not buy influence or friends. In an attempt to earn time off for good behavior, Capone became the ideal prisoner and refused to participate in prisoner rebellions or strikes.
