George Conte manhandled Salvatore Avellino.

I mentioned the Masucci/Mangano story in another thread.

Anthony Di Lapi supposedly intervened to stop Al D'Arco bullying people in prison, don't think it got physical.

Anthony Casso was beaten up by a mobster in the clink, can't remember his name.

I invoke my right under the 5th amendment of the United States constitution and decline to answer the question.
