As of right now there is no concrete information available that confirms Meech told on anyone. The paperwork being displayed does not directly state he cooperated. People are telling others to "read between the lines" and "put 2 and 2 together" but that's not the way it goes in situation of this caliber. There needs to be concrete proof.
Another thing. Cuffy is not currently incarcerated because of Tammy Cowens. He is doing time for Murder, nothing to do with the situation being headlined. From what Cuffy said the Feds had to throw out entire indictment with Tammy because she was caught sleeping with her DEA handler.
Those are some of the FACTS I've gathered from this situation.
