Michael Jackson suffered another setback in his child molestation trial today. After hearing pre-trial motions in the case, Judge Rodney S. Melville has ruled that the prosecution can introduce testimony from an expert witness on common misperceptions and myths about child molestation and the actions of the victims of this crime.

The prosecution indicated that the witness would testify about why there is often a delay in reporting acts of child molestation, why victims often remain close to their abusers and why they may not tell close relatives anything about the incident or not tell a complete story when they finally do divulge what happened.

The prosecution hopes to use this testimony to explain some inconsistencies in the alleged victim's statements to social workers and other people given since the case was first reported.

Jackson's defense attorney, Thomas Mesereau Jr., that the testimony would prejudice his client's case to the jury but the judge ruled in favor of the prosecutors.

Jury selection in the case against the 46-year-old 'King of Pop' is scheduled to begin January 31. Jackson is accused of sexually molesting a 12-year-old boy after giving him alcohol to get him drunk. This is the second time charges for molestation have been brought against Jackson. The first case was dropped after an out of court settlement was reached in a civil lawsuit.
