I'm quite surprised at your responds guys. Many threads have covered both issues:

1. There are hundreads of known rats that are living out quitely, even those who were members of more powerful, wealthier and larger families.
It's not a priority. There is money to be made and "things" to be re-organized after the indictments.
And he's gotta be watched 24/7.

2. If the indictment covers just those two things it doesn't mean that the whole organization is involved just in that.
AND since when gambling\shylocking is low level? Just because it doesn't sound as fancy as "labor racketeering" it doesn't mean that you can't make tons of money.

Loan sharking and gambling have been the backbone of the LCN all these years. They know that it's a secure income...there's always going to be. So they can invest that money in other stuff
and God forbid some actions get stopped, you now that you can rely on that money monthly.
