I'm sure a lot of guys in Brooklyn suspected he may have been a rat. But because they knew he was a half a nut job lots of guys also feared him. So they kept quiet.
I believe that may be the "true" reason why Greg's brother Sal Scarpa was set up and killed. Because he may have found out about Greg and confronted him about it. Or was threatening to tell the borgata. (my personal opinion on this matter). In my own mind I wonder if Greg killed his own blood to keep that secret...He never made an inquiry, or a squawk about Sal's death. I find that a bit strange.
This whole thing began when Greg found out about Matty Ianiello (not the horse) being an informant. Matty was close to Sal. The theory is that Greg warned Sal about Matty but Sal didn't like what he was hearing. I wouldn't be surprised if Greg admitted to his brother how he knew which probably caused a nasty reaction from Sal, who was known as stand up as they came. Intel later revealed that Philly Paradiso was part of the hit team. He was also the only member of the hit team who was masked, the only one who was unarmed and the only one who was white too. Yeah, they used black guys! Needless to say, the masked guy is the one who pointed out Sal. Never do a hit inside a crowded social club, especially with Messy Marvin inside lol
