Look, I understand that you're just looking to have a tantrum on the internut at this point, but....
Nobody is talking about "street cred". That's a stupid metric for whether someone can have any sort of valuable opinion regarding a training class. Frankly, the last person's opinion I want is some SWAT cop or SF guy. What I'm interested in when someone reviews a course is what other courses they've taken so that when they say "best class ever" you have some context for that.
