In the 2015 prison brawl with the Albanian Rudaj gang members, LCN members seemed to have called on their allies in prison gangs to beat the two Albanian inmates up, there are reportedly 25 people involved in the fights but only 5 are said to be mobsters, it`s likely that they still have a lot of friends in prisons like Hispanic and White gangs with whom mobsters usually form a relationship. https://www.cosanostranews.com/2015/03/in-danbury-prison-albanians-mobsters.html
You basically never hear of mobsters fighting with other gangs, they are always, always working together.
