MJ was only accused of the crime you write about. Horrible though the crime is, a jury found him not guilty. In our legal system that means he didn't commit the crime (well, actually, that the prosecutor failed to prove that he committed the alleged crime). In any event, it means that for all intents and purposes he didn't commit a crime...and, while it is ture that Elvis only hurt himself, he and others (like Dr. Nick) were, arguably, involved in a illegal activity.
Look, I'm not excusing Jackson. I think the mourning over his passing is completely overblown...but it is entirely in keeping, I think, with the level of public focus on the death of similarly high-level celebrities. The argument that he was a pervert (possible) and there for should not receive the kind of public adulation he is receiving, while understandable, also seems to me, as I said above, to create something of a double standard. Of the three celebs I mentioned, Jackson is the only one to be specfically found not guilty of an accusation...
