Not beyond reasonable doubt

The coroner has ruled Michael Jackson's death a homocide. He seems to have overlooked the possibility that the desperately addicted Jackson might have awakened during Dr. Murray's bathroom break and injected himself with an additonal overdose of propofol. Thus it could have been an accidental suicide. Alternatively, a member of his family could have done it.

I'm sorry to inflict you with yet more of the endless comment on Jackson, but this seems instructive in how to evaluate evidence.
