In a new case of political retribution involving Mumia Abu-Jamal and constitutional rights, Pennsylvania lawmakers have approved a measure that critics say tramples free speech. The measure authorizes censoring the public addresses of prisoners or former offenders should judges agree that allowing them to speak would cause “mental anguish” to the victim. The measure was approved after Abu-Jamal delivered a pretaped commencement address for graduating students at Vermont’s Goddard College earlier this month. Abu-Jamal’s speech was opposed by Pennsylvania state officials as well as the widow of Daniel Faulkner, the police officer whom Abu-Jamal was convicted of killing. Pennsylvania Governor Tom Corbett is expected to sign the measure into law. The American Civil Liberties Union of Pennsylvania has criticized the measure, calling it “overbroad and vague,” and unable to “pass constitutional muster under the First Amendment.”
