I saw a different documentary years ago with a different fbi guy taking credit for putting in the Castellano bug. A ret fbi that looked like a cheesy Ric Flair. Both stories I believe involved tv repair.

But the older doc the guy said that he BS’d his way into getting it in a cabinet near a kitchen table. On this one a different fbi dude says that Billoti held a flashlight for him as he put it in a tv.

These stories always change a little.
