We don't often here much about the Mafia here mate. The last few events regarding the wiseguys that i've heard has been the deaths of Joe Bonanno and John Gotti. And a few busts involving the Genevese family and an undercover cop early last year sometime.
Americanmafia.com used to be good for latest news but it's never brought upto date anymore.
Jerry Capeci's Ganglandnews.com is one the best sites for past and present information.
The five Families are still active in NY. But ever since the Commission case in the mid eighties La Cosa Nostra has just been taking severe blow after blow. Top guys arrested quite often. There's a good thread about the current bosses in this forum somewhere.
