Georgia's Board of Pardons and Paroles will consider whether to grant clemency to death row inmate Troy Anthony Davis Monday.

The board will hear from his execution's supporters and opponents.

Davis' case has attracted worldwide attention in part because no jury has heard evidence of witness recantations in his case.

Seven of nine witnesses have taken back their testimony incriminating Davis in the 1989 murder of Savannah police officer Mark MacPhail.

The slain officer's son, Mark MacPhail, Jr., plans to attend, along with many in his family.

MacPhail says, Davis' execution is overdue.

"To take 22 years to get justice is very much so a slap in the face to everyone who wears a badge," MacPhail says.

Davis will be represented by his lawyers and his family, who intend to stress the uncertainty in the case.

University of Georgia Law School professor Donald E. Wilkes, Jr. says, there's too doubt in Davis' case to carry out an irreversible sentence.

"They have said that they will not uphold an execution unless guilt was certain," Wilkes says. "And so, by their own standards, the Georgia Board of Pardons and Paroles ought to reduce his sentence to life without parole."

Barring any last-minute change, Georgia will put Davis to death by lethal injection on Wednesday.
