A proffer is a “ testing the waters” type thing. Sometimes guys/ lawyers do it just to get a hint of what the feds have as far as evidence or strategy. Thats basically what Gotti Jr did and no arrests resulted.
Both he and gotti jr did a lot of prison time so they certianly never coughed up anything valuable and both had tons of info they could have given.
None of those two took the stand or wore a wire. Alite went full blown rat.
