Philando Castile did what you are supposed to do if you have a concealed-carry permit and get pulled over by police: He let the officer know he had a gun. Had Castile been less forthcoming, he would still be alive.

Last Friday a Minnesota jury acquitted the cop who killed Castile of second-degree manslaughter, demonstrating once again how hard it is to hold police accountable when they use unnecessary force. The verdict also sends a chilling message to gun owners, since Castile is dead because he exercised his constitutional right to keep and bear arms.

Jeronimo Yanez, an officer employed by the St. Anthony, Minnesota, police department, stopped Castile around 9 p.m. on July 6 in Falcon Heights, a suburb of Minneapolis and St. Paul. The official reason was a nonfunctioning brake light.

The actual reason, according to Yanez, was that Castile resembled a suspect in a convenience store robbery that had happened four days before in the same neighborhood. The full extent of the resemblance was that Castile, like the suspect, was black, wore glasses and dreadlocks, and had a “wide-set nose.”
