I don't think it deluded to believe him innocent, because after all he was never convicted and most of the evidence isnt available to us (though hardly anyone ever is convicted of sexual crime). It's a perfectly legitimate position, as long as you acknowledge that you could be wrong in thinking it - we could be wrong in believing him guilty too, of course. Basically it's a tragedy for those kids, either way.
tbh I only know a little about the whole thing because it was never of that much interest, but this:
"Jordan Chandler has been telling people for years that Jackson didn't touch him. Jackson's defence team had a long line of people ready to testify to this in his 2005 trial."
isn't really any kind of an argument. I read the same article, after all you linked to it, and it's just repeating rumour and hearsay by his openly admitted strongest supporters.
Look, his team can say anything (as can the other side, of course) after a trial, and none of it is provable. Doesn't alter the fact that his actions were dodgy, he never sued for libel despite extremely explicit claims, he seemed to find vulnerable kids with appalling parental relationships and get them to sleep in his bed (badmouthing the parents is not really a defence strength, given paedophiles tend to target precisely such kids for obvious reasons), 3 kids apparently said he molested them and were willing to be publicly named as homosexual abuse victims in a hugely public trial that would make them even more infamous than Monica Lewinsky - quite an incentive to deny everything - Jordy Chandler did make these claims to a psychiatrist as well as his father, Jackson's own sister stated he was guilty of child molestation, and I can't really see much way he was innocent given his behaviour and known predilections, BUT... his death was a tragedy for his family and loved ones, just the same. And this death is, too. I loathe the sentimentality over the one and the ghoulish gloating over the other - really distasteful and unpleasant. A youngish person killing themselves (with drugs, or a gun) is always a waste, and awful for the survivors who love them.
