Who, on this half-century anniversary of Cronkite’s commentary, can match his credibility and authenticity?

I nominate the students and teachers of Marjory Stoneman Douglas High School.

Wayne LaPierre of the National Rifle Association has attacked the “media.” But his real targets are the eyewitnesses to the horror at that school. Those are the people who have brought a new credibility in the national discussion. They are the young veterans with back-from-the-front authenticity.

Consider the Parkland, Fla., teacher Greg Pittman and what he has had to say about carrying a handgun into class with him: “One, where do I put the gun? Do I put it in my pocket in a holster? In my desk? Is it locked up somewhere? . . . I am in the profession to teach. I did not sign up to be SWAT, to be a policeman.”
