U.S. protesters campaign against death penalty in Philadelphia, 2000
In 1981, former Black Panther Mumia Abu-Jamal was accused of murdering Daniel Faulkner, a police officer in Philadelphia, Pennsylvania. A series of discrepancies emerged in the trial, which took place in June 1982. Although Abu-Jamal insisted that another assailant shot Faulkner, the police found two witnesses who claimed to have seen Abu-Jamal commit the crime. One of the witnesses, a cab driver, changed his testimony from the original story given on the night of the crime.
