As the Trump administration takes on the latest wave of left-wing violence, an obituary reminds us what happens when political killers get away with their crimes. The law never caught up with Joanne Chesimard, aka Assata Shakur. Stanford University’s dean of students, Mona Hicks, quoted a “loving refrain from Assata Shakur” in a campus email at the time of the George Floyd riots:It is our duty to fight for our freedom. That language wasn’t metaphorical—when Shakur said fight, it was a call to violence. This time the country, including government and the universities themselves, will have to react differently: There must be no tolerance for such political violence.
