Frank Dux (true or false)

[TraininDummy]

I came across this during some random researching and had to be a skeptic. Getting a movie deal is one thing, but claiming to be a former covert operative for the government and training government personnel is another? The whole deal sounded a little off to me but I'll ask you gentlemen. Have any of you ever heard of this guy minus Bloodsport or ever trained with him. If so, was it worth while or a complete waste of time.
