I doubt it. If they can get to the guy before he testifies, then maybe. After, and they run the risk of the Feds going batshit. This ain't Sicily (or even Canada), and even the Sicilian born members here know it.

The Feds just won't tolerate the murder of someone that they're supposed to be protecting. It makes them look weak. The bosses here are smart enough to realize that.

There are so many rats living out in the open in America it's crazy. A lot of them even have Facebook pages! Paciello is just the poster boy.
