The trial of the physician charged in the 2009 death of Michael Jackson is set to begin this week in Los Angeles with jury selection. Dr. Conrad Murray is hoping to be found not guilty of involuntary manslaughter. Jackson had an addiction to prescription pain pills and Murray’s defense team had wanted to introduce evidence of Jackson’s addiction at the trial, but Los Angeles Superior Court Judge Michael Pastor barred the testimony. Murray’s attorneys wanted to have about six physicians testify about the validity and extent of Jackson’s drug addiction. “The deck is, for various reasons, stacked against the defense here,” said Stan Goldman, a professor at Loyola Law School in Los Angeles. Murray admitted giving Jackson propofol to help the pop star sleep. Propofol is a powerful sedative that is usually administered by licensed anesthesiologists in a hospital. Jackson’s death was attributed to an overdose of propofol and other powerful drugs.
