Will Michael Jackson Rehearsal Footage Prove or Disprove Conrad Murray Defense Theory?

Video of Michael Jackson's last two rehearsals for his 2009 "This Is It" tour could be played in court during Dr. Conrad Murray's manslaughter trial.
The L.A. County District Attorney filed a motion today asking the judge to allow the rehearsal footage from June 23-24 to be entered as evidence.
The D.A. believes the footage supports the testimony from "This Is It" director Kenny Ortega that Michael was "happy and excited for the future."

It also opposes the defense's theory that after the last rehearsal, MJ became desperate and "took desperate measures that caused his own death."
The D.A. also filed a motion to allow limited photos from MJ's autopsy, claiming the pictures are not gory or gruesome and won't prejudice a jury.
