Why shouldn't I trust Jesse Ventura?

I have seen most of those "Conspiracy Theory with Jesse Ventura" shows on the TruTV channel and I have now become a believer in Ventura's work. In fact, ever since I saw the episode that seemed to prove that an airplane did not crash into the Pentagon I've started to believe that 9/11 was a government conspiracy that was done as an excuse to go to war and abolish Constitutional rights! However, many people who I have told this to have told me that Jesse Ventura is not someone who should be trusted and is certainly not someone who I should have faith in. Well, can someone please explain to me why a former governor who also spent time as a pro wrestler and navy seal cannot be trusted? Considering that Jesse is willing to reveal information that most politicians would want kept secret, I think he is a great person to trust.
