The Hispanic gangs are now stronger than the mob, and willing to go after informants. To say they are not smart enough is way off, they are ahead of the mafia in thinking, and have political clout due to race, which the mob doesn't have. The Hispanic gangs were the first to use electronic devices like pagers to set up calls from safe phones in the days before cell phones. Plus there are way more of them on the streets, but way less of a percent in prisons. Part of it of course is the government prosecutors obsession with making Mafia busts.
