tru the community is aware of its surroundings thats a key factor in the "advertisement", i guess back in a certain time the mob members wude go to the buisness's and ask for theyre buisness in return as done in "The Untouchables" when the store keeper does not except the illegal whiskey from Al Capones crew, the store is Blown to Bits. So intimidation was also a factor as well. But times change, but im guessing the strategies are still similar in some ways like the old days.BTW where did all the fire arms (guns) come from. How were they available to Mobsters with such availability?
