Mafia killed mafia, thus the regular people were, for the most part, unaffected. This crime we see today is completely different. Now, to be a gang member you have to kill an innocent person. They target the civilian population as a policy.Of course it is real. It was real in other eras. That wasn't "TV" It is history. People died.then too. Nothing has changed. What is your point?
The mafia never did that.
