First off, let's remember that Michael Jackson was acquitted of his charges. It doesn't necessarily mean he was innocent but it does mean the law let him off, and they know far more about it than we do. Jackson was a strange man who did some questionable things, and it is weird to me that the media, who has spent the last decade or so blasting him for every little thing, suddenly has done a complete 180.
That being said, I agree with you somewhat, although I haven't heard anything about McNair being an alcoholic. I haven't really gotten a real negative attitude from the media, they're focusing on what happened around the time of McNair's death, which is the story right now. It's the fans' reactions, like the judgmental moron Reed Space who posted on here judging McNair at the top, which is what gets me. I bet these are the same people who think women deserve to get raped for being out at night or who think you deserve to be robbed for going through a bad neighborhood. You'd think McNair was a serial killer the way people are acting. McNair's actions shouldn't be condoned, but they should not have resulted in his death.
