The problem is, once charges are officially filed and an arrest made (probably only ONE arrest), it would be much harder if not impossible to re-open the case. The official investigating would be officially DONE, then. What I fear the most is that the most obvious person will be arrested and will take a minor fall. He may expect money down the road, or may have been threatened to keep quiet. I think the real perps are probably very high-level, and are virtually untouchable for political reasons. That's why I hope (but do not expect), some of those who worked on TII to come forward.
What we don't know, and what there is conflicting information about, are (among other things):
What was Michael's health, really? If he was not in shape to do the concerts, and people knew that, they he was worth more dead than alive.
How many rehearsals did he really attend? There is a lot of conflicting info about that, but those who were THERE would know. Even if it's only a guy who was doing to lighting or sound, he would know if Michael was there, or not there.
Who hired the body-guards. Specifically, WHO hired them and gave them orders?
Why did the info about the missing Security tapes. . . go missing from the news? Were they really missing? Have they ever been recovered? Who took them? Who would have had access and motive to take them?
(We should probably have a thread specifically devoted to just QUESTIONS. Maybe later, or someone else can start it?)
