The Trail at Yale.

Investigators try to ascertain exactly what happened at Yale Law School yesterday. At first I figured it might have been some disgruntled Kaczynski type. But now that it turns out the alleged bomb exploded in a classroom rather than the mailroom, my guess is some bored Elis were testing out their copy of The Anarchist's Cookbook. Either way, two random classrooms in New Haven seem an unlikely target for Al-Qaeda.
