Yeah, he would have been better to stay focused on a relatively small group of serious charges and just build the case up in intensity instead of diluting it with the side charges. The conspiracy charge was a bad idea - I never did get that whole thing anyway, and the crazy mom was a disaster. The DA didn't do a good job. That said, I'd still have found the SOB guilty on something anyway as there was certainly enough evidence to produce reasonable doubt of guilt as we all know he's a pedophile.
I think much of the problem lies in the circus atmosphere, huge load of issues, and the horrendous lengths of these trials. Out of the major trials out there in the last several years -- OJ, Peterson, Blake and now Jackson -- only Peterson was convicted No one can tell me that in the other three, the jurors were at fault.
Judges need to get a grip on the proceedings, make the lawyers focus on one or two key issues, hold down all the unnecessary witnesses (what did, for example, Macauley Culkin really contribute as a witness here) and keep the length of these trials down to a max of 2 weeks, maybe shorter.
