Even if the current crop of boot camps is all awesome, it's an ideal model for a scam. With new ones popping up all the time, anybody with more greed than sense could open up a well-marketed school, make some great promises, collect a couple hundred thousand dollars, give some half-assed classes, and shut it all down again before the first bad Yelp reviews come in. And then they could do it again with a different name instantly.
If you really care that much you just need someone that knows the subject to go the classes and see for themselves if everything is being taught good enough. You don't need to inject a bureaucratic debt in their finances in the name of "regulations".
