I’ve heard a fair share of second-guessing about how the police and the administration in Blacksburg handled yesterday’s terrible events, particularly how slow they were to notify the campus about what was going on. I don’t pretend to know whether and to what to degree they were wrong, but it seems pretty obvious to me that every school in the country should have a Twitter channel and require every student and faculty member to sign up for it.
Yeah, a lot of people would turn off their phones in class, but plenty of them wouldn’t, and the people outside of class may have been able to identify the shooter before he got to second crime scene.
