ARRESTED: Raymond Clark III Charged With Annie Le Yale Murder

It's a story that captured our attention for the past several days. A graduate student, just days before her wedding, walked out of a campus building at Yale and vanished--only to be found, sadly, stuffed into a wall at that same building.

What we can't forget is that Ms. Le was a victim of workplace violence. If early reports have any validity, her alleged attacker (who worked as a lab assistant where she conducted her studies), spurned in his attempts to force her to operate in "his" lab the way he wanted, killed her.

My question to all of us is this: Are we certain that we're doing the work of screening workers and others who enter our workplaces for potential threats? Yale is in the heart of an urban area, but the threat to Annie Le came--not from random big city violence, but from within the university.
