This is exceptional news! Despite the very clear video evidence it took eight months to file charges, and I don't think it would have happened at all if it weren't for the Ferguson riots and "Black Lives Matter" protesters (in addition to all of the Albuquerque protests and the Department of Justice investigation).
I have my doubts that the charges will stick, though. A District Court justice has to decide that there is enough evidence for murder at a preliminary hearing (where the charges may be downgraded or dropped). But still a better chance of going to trial for something than the ol' grand jury shenanigans.
Even if either officer goes to trial on any charge, I don't expect a conviction. When Kelly Thomas (an unarmed homeless man in Fullerton, CA) was beaten to death by police (captured on both video and audio recording devices) two cops were charged with involuntary manslaughter and one with murder. But after the first trial found two of the cops not guilty, the DA dropped the charges for the third cop.
