Earlier month, attorneys for ex-NYPD cop Peter Liang, who, in February, was found guilty of manslaughter in the shooting death of Akai Gurley, filed a motion arguing that Juror No. 9, Michael Vargas, should not have been allowed on the panel. His estranged father, it turns out, served time for manslaughter. Vargas also made a number of anti-cop comments on Facebook.
