The prevailing wisdom holds that law professors are wise to wait until they earn tenure before they start sharing their opinions in the rough-and-tumble legal blogosphere. Dan Markel wasn’t interested in waiting around. He launched his pioneering PrawfsBlawg as soon as he landed an assistant professorship at Florida State University College of Law in 2005—even before teaching his first class.

So it seems fitting that the reaction to Markel’s July 20 shooting death was immediate, intense and to a large degree expressed online. Scores of law professors have shared their shock and grief on the Internet, and readers rushed to the PrawfsBlawg comments section to offer their thoughts, memories and condolences.
