Just being curious: were there any mafia leaders to have served time in Alcatraz apart from Al Capone and Charlie Carrollo?
And by the way, how did those 2 end up there anyway? I mean, they were murderers, but "formally" they were just tax evaders, being convicted only for this, so how did they end up in a prison for people convicted for dangerous crimes?
Not saying they didn't deserve it, just wondering what the "formal" reason for transferring them there was.
