I'm sure more and more now that they have La Scarola bugged, just like other known mob spots.

Here is an article that mentions now FBI and NYPD wiretapped different part of the Genovese's Triangle Social Club. I know different city and different family, but the authorities know the common hangouts and can bug a place instead of just a person.

I'm guessing La Scarola, Gene & Georgetti's, etc are all bugged.
I have a vague memory of a place like Billy Goat Tavern or some other city hangout being wired because so many politicians went there for lunch (this was about 20 years ago or so).
