Betcha Robert Friedman, who has written a book on Meir Kahane, a subsequent book, ""Zealots of Zion: Inside Israel's West Bank Settlement Movement, " and a recent one on the Russian Mob, "Red Mafiya, " is a good source.(While doing the journalism for the latter, Friedman found it wise to temporarily find other living quarters due to death threats. The NYT was publishing his work on the Bank of NY money laundering.)
