Serp, you have been suggesting how they should use lie detectors and strip down for meetings and such. Although it sounds a little ridiculous. So does sitting in prison for the rest of your life. It's better to air on the side of caution.
Regarding Lefty, why didn't they kill him in prison? What were his prison years like? Did he have the protection of being a made guy or was he all alone? He probably wished he got the Sonny Black special rather than being locked up for twenty years thinking about he let a Fed destroy his borgota.
