This is what I can call...HOAX!
Okay suppose Michael is dead...
Who had to take care about releasing the video? Akon and the family,right? 1
now the other situation
That guy supports Murray so he thinks Michael KILLED HIMSELF,right? If Michael would be dead,Akon would accuse Murray and I think everybody agrees. 2
1+2 => why would akon let that guy play in Michael's video as long as he ACTUALLY wants JUSTICE FOR MURRAY?! (because I guess he thinks Murray is accused without any real reason)
