Well if you get an invite soon to join a group of “local boys” who are also mad at the current situation, you might be cautious. If there are nine other guys at the first meeting, odds are better than average that at least eight of them are feds or informants and the jury is still out on the skinny squirrelly little guy who has a tiny “regulation type” mustache (doesn’t touch his upper lip) who sits in a dark corner and doesn’t say much.
Completely not my style. I’m not a joiner.
