Judge dismisses murder charges against Philly cop in shooting death, DA vows appeal

Philadelphia police officer Mark Dial was charged with murder in the shooting death of Eddie Irizarry during a traffic stop in August.
Judge initially dismissed charges citing lack of evidence and possible self-defense, outraging Irizarry's family.
District attorney refiled charges and plans to appeal judge's decision to dismiss.
Defense argues Dial thought Irizarry had a gun, while video shows Dial shooting Irizarry at close range.
Case dismissal has sparked community anger and protests over police accountability.
