its a question of numbers the states are too wide and the mafia today has little men to run that country as a whole most of places know the mafia only through movies except new york and a few others
for example a crime family with 50 made members in a little city would be feared by every criminal elements, but in big city of 3 millions of people the percetpion of local people and other would be far less
canada is far smaller and there are several mafia members thats coz is different there
in italy the mafia is feared by everyone, all outside crimnals and all citizens since its everywhere even outside its strongholds in the south and its run everythings included all the prisons across the country
