The foreman of a jury that acquitted a white Pennsylvania police officer of homicide says the Michael Rosfeld didn’t know the black teen he shot was unarmed. Juror Jesse Rawls Sr. says Antwon Rose II and another occupant who ran “brought it on themselves.” He says the then-East Pittsburgh officer knew there had just been a drive-by shooting. Hundreds of high school and college students protested the verdict Monday in downtown Pittsburgh.
