Supporters of political prisoner Mumia Abu-Jamal are raising alarm after a judge on Friday denied his request for a new trial. Philadelphia Judge Lucretia Clemons dismissed evidence the case was tainted by judicial bias, police and prosecutorial misconduct, and that key witnesses were bribed or coerced. Mumia is 68 years old and suffers from numerous health problems. The journalist and former Black Panther has maintained his innocence for the four decades he’s been in prison after being convicted of murdering a police officer.
