A New York City man who was at most guilty of selling loose cigarettes on the street was tackled and placed in a chokehold by a police officer in late August. The man, Eric Garner, protested that he couldn’t breathe, but the officer with his arm around Garner’s didn’t let up. Today, a grand jury announced that it would not indict the officer, Daniel Pantaleo.

I’ll leave it to the legal analysts to rehash the evidence presented to the Pantaleo grand jury. Hopefully there will be a transparent accounting of what was introduced. But the fact that two grand juries in fairly rapid succession have failed to indict police officers involved in highly questionable deaths of unarmed black men should give us all pause. In Panaleo’s case, the grand jury’s refusal to indict him despite his use of dangerous and violent tactics doesn’t pass the smell test. Add in historic patterns of NYPD abuse against black men in New York—Amadou Diallo, Abner Loiuma, stop and frisk generally—and the lack of an indictment downright stinks.

The failure to indict the officers who killed both Eric Garner and Michael Brown deprives their communities of the transparency and accountability that trials ensure. No one is saying that the officers should be tried if there’s not sufficient evidence, but many legal analysts have agreed there’s enough in both cases to at least warrant a trial. There are questions about facts in terms of both Michael Brown and Eric Garner’s movements before their death, questions of fact that should be debated in a court. There are questions about the officers’ states of mind—questions that could be fleshed out and better understood if the cases went to trial.

But the lack of indictments, now twice in a row, seems to add insult to injury—that not only are black men routinely, disproportionately victimized by the police but they are victimized by a legal system that refuses to hold the police accountable.
