This was another great episode. Judd Hirsch is finally allowed to flesh his character out and into something more than a slightly over-protective father.
I like how they went into the FBI's shady past. A lot of shows make it seem like these various agencies can do no wrong, so it was nice of them to acknowledge the crimes of the past.
This episode shows just how good a person Don is. He's not going all John Wayne on us, but rather he is allowed through his dialog to make social commentary that shows he is a thinking man and not just part of a machine.
However, I don't think the bombing of the statue at the college was a copycat bombing like everyone thought. It was totally an art critic. And you KNOW that everyone (while "shocked" at the bombing) was secretly rejoicing at the destruction of the horrid thing. Admit it.
