My only explanation to this would be that they would choose whatever was close and easier to get to. Don't forget that travelling was way different back then.

My only explanation to this would be that they would choose whatever was close and easier to get to. Don't forget that travelling was way different back then. I've heard stories of fleeing to Mani, Sicily and Egypt. I guess each family, or person was choosing the easiest place to get to by his own means. Now why they stayed there and didn't e.g move up to Genova, I have no idea. Maybe some people did, some others didn't. On your second point, I feel like organised crime in the US is and I'd say in the world to an extend is made up by groups that tend to be foreign to that Country. If you take it by todays standards and leave out the Italians in Organised crime that have the means both political and economical to do what they do, you have other groups like the Albenians that tend to influence things using pure muscle even nowadays. Here in Europe the Albenian mafia seems to have a very powerful crew, most of its power doesn't come by political factors nor economical, but by manpower and muscle (e.g members of the albenian mafia won't care if they will be jailed, they are just going to act). Same applies to some other groups e.g form Afghanistan that run drugs etc. My opinion on that is that they tend to be tougher due to having participated in wars. Imagine an Afghan boy that lived through his whole family teared apart and seen death in a war, smuggling his way in London and instead of Europe helping him get on his feet, there is a group of his own people that offer him a few bucks in order to go do something illegal. Btw this has nothing to do with Afghans, its just an example, I have nothing against them.
