The guy who killed Cali is under HEAVY protection, it's just unrealistic to expect anything there. As far as street gangs taking their turf, you have to understand that the Mafia these days are seeking areas that street gangs can only dream of, such as union control, business infiltration, finance through loansharking, in other words the more sophisticated stuff. But you are right, the days of cold-blooded multiple murderers are over for LCN. People can say what they want about tougher laws or whatnot, but the fact remains that back in the day they had guys who didn't give a fuck, life sentence be damned. And the Mafiosi from the old country are the only hope that the American Mafia has to continue on, I strongly stand by that.
