Can there be a fair jury and transparency in a case where a white cop killed a black teen? Time will tell. Prosecutors twice on Wednesday accused defense attorneys for Chicago police Officer Jason Van Dyke of purposefully eliminating black jury prospects in the Laquan McDonald case. The latest accusation came after the defense used a peremptory strike to cut a 22-year-old black man who only answered half the questions on his jury questionnaire and said he read negative Facebook posts calling Van Dyke a murderer. Prosecutor Dan Weiler said the cut was evidence of a larger pattern of striking black jurors: "The only reason he was struck was that he was a young African-American. This juror gave answers that clearly indicated he was a fair juror."
