I’m not the one with the expertise. What I’ve read is Pagliano does not have full immunity. He’s still on thin ice and needs to keep mum since he can possibly incriminate himself in some other way.
“limited immunity”
Yes. In addition, the limited immunity order probably clearly outlines the areas of investigation.
The FBI won’t want anyone to know that, and Pagliano’s defense team will want to blur the lines between what’s covered and what isn’t to deflect ALL questions about Hellery.
