I do not think that Turnbull is relying on street knowledge. Therefore, he should cite an authority, a book, an article, for his claims.

Balagula was definitely Jewish. His later rival Vyacheslav Ivankov was not a Jew.

Since the fall of the USSR in 1991, a greater percentage of Russian immigrants to NYC have been gentiles, and so too a greater percentage of the Russian Mafia in New York has been gentile.

But on the whole, the Russian mafia in New York is a predominantly Jewish affair. This is a fact. And to state simple facts does not constitute or "feed" anti-Semitism. On the contrary, white-washing certain facts promotes anti-semitism as to do so breeds a conspiratorial mindset where facts do not matter
