“Walter could have you up on the betting laws too, but Wolfshiem scared him into shutting his mouth.”
Before Tom was just making broad statements about Gatsby being a bootlegger that didn’t really phase him. He mentioned a few of his associates too, but Gatsby knew that just throwing out a few names wasn’t really going to damage him. But now Tom is starting to drop some of the information he gathered when he got some men to look into Gatsby’s affairs, and making specific accusations that are a lot more effective than just calling him a bootlegger.
