One version coming out earlier and one coming out later does not make one more credible over the other. The fact that this young man's family is trying to get the "I am Treyvan"phrase registered (if true) would explain why they don't want any of the less palatable aspects of their son's life coming to light -- I know it would make me angry to see all that potential money going down the drain. Everyone wants to embrace them when they feel their son is a sweet, innocent young guy; less so when he's been shown to get into fights and is suspended from school for drugs. But some of those facts, if true, need to be made known, because they paint a picture of a young man, prone to confrontations, and possibly, violence, himself. Behavior that could support a self-defense plea.
