I'm with starsnuffer and chinamigarden on this...I'm going to go with the belief that what the guy says is true as happened. He is now a registered sex offender for something he did as a 18yr old, with someone who he believed to be close to his own age....it does not in any way make him a predator or pedophile. Thats one thing i dislike about the registry...might as well brand someone on the forehead for something that may not of been as bad as it really was. Not saying always, but the registry paints with a pretty broad brush. That said, unless you see any reason to make you believe otherwise, I would just treat him as any other stranger who stops to watch a practice/game that you don't know.
