The case of Bijan Ghaisar has enshrined injustice

The killing amounted to an execution by officers sworn to uphold the law, who appeared exasperated that Ghaisar, perhaps terrified that the officers had approached him with guns drawn, drove off twice after being stopped before the final, fatal encounter. To be clear: Exasperation does not give police a license to kill. Or at least — we would have thought until this decision that it does not.
