I think you could be right!
I was waiting to hear the newspeople say that he lived in Colorado at some point or taught at the elementary school. I've not heard that he has friends in CO, so why would he be at the Ramseys on Christmas night? How would he have known about JonBenet in the first place unless he was a regular patron of kiddie pageants. And why would his former wife vouch for his whereabouts that evening? Why protect a convicted child molester? Through his book research he has had a lot of opportunity to be contacted by the real killer, and he looks like a nobody, seeking publicity. Lots of unanswered questions.
