On Saturday, an attentive security team spotted a white man behaving suspiciously on the campus of an historically black university in Jacksonville, Florida. Having drawn their attention, the man left and ended up at a nearby Dollar General store. There, he murdered three African Americans in cold blood before killing himself at the scene.

Responding officers found a swastika painted on one of his weapons. When they searched his home afterward, they found racist argle-bargle on his computer.

On Monday, at the White House, a reporter for NPR was keen to know how much blame, precisely, the governor of Florida bore for the attack.
