Yale Divinity School invited Black Lives Matter activist DeRay McKesson to be a "guest lecturer" for two days on "transformational leadership." McKesson made it clear just how transformational his leadership was when he defended looting as a legitimate political tactic. On Friday, McKesson will be one of the BLM activists meeting with Hillary Clinton. Perhaps Mrs. Clinton could broach the subject with Mr. McKesson and get his views on whether killing white cops is justified.
