In 1970s, radical African-American activists squat in Philadelphia home; they pace around the roof with firearms and hold forth with loudspeaker, which annoys the neighbors. In 1978, during massive police operation to evict the group, an officer is shot in the back of the neck. (There is speculationthe officer was hit by friendly fire.) Nine activists are convicted in his death. Two die in prison; two have been released on parole; and two more are suing over being denied parole. Eastern District of Pennsylvania: The parole board needs to turn over victim impact statements to the activists; the statements could shed light on whether the board’s reasons for denying parole were arbitrary or pretextual.
