That was terrible. Proctor literally said that he wasn't going to snitch, then in the very next scene, he snitches.
I get he was trying to protect Ghost because he knew Saxe wouldn't believe the truth, but he didn't think that would get back to Tommy? Season five Proctor would have slapped season six Proctor for doing that.
Ehhh Tommy only found out because the writers wrote the law enforcement side of things incompetent as hell in having them always give out more information than they had to. There was no reason why Saxe should have mentioned his name to Maria Suarez outside of convenient writing and having Tommy pull off unrealistic murders like a madman.
