Preliminary jury selection begins today in the involuntary manslaughter trial of Michael Jackson’s doctor, Conrad Murray, charged in Jackson’s 2009 drug-related death. It won’t necessarily be easy. Before the trial was postponed in May, it took three days just to secure a pool of potential jurors who weren’t already familiar with the case. Last week, the defense requested another delay while the court determined whether the jury ultimately could be sequestered so that it wouldn’t be “poisoned” by media coverage, but an appeals court denied that request yesterday, according to CNN. Direct questioning of qualified jury candidates will begin Sept. 23 and opening statements are expected four days later.
