Not really if his point is what I read out of it. He could have been a really good kid who stayed out of trouble, played sports and was indeed the portrait of what many have in their minds, spoon fed from the media.
Many kids act out when their parents get divorced. It depends on the kid and circumstances. Some close up, others act out violently or do things with people they would not normally have sought out to hang with.
So what I read him saying is that as a possible result of his parents divorce he may be troubled, acting out and inclined to doing things or acting in ways he may not have just a couple of years ago. Such as, possibly approaching the man idiotically following (after ditching him and seeing him retreat to his vehicle) and asking if he had a problem. When told no, to possibly go off on him and give a beat down.
That, if it happened that way as reported, may be something that never in a million years a younger Trayvon would have done. That's what I got out of it. I don't see it as the divorce caused it.
