Sniper's latest victim was FBI agent

Oh, boy. Presumably she was targeted at random, like all the others. But still...

As for "Is this terrorism?" I of course have no better idea than anyone else. It may be that this is a thrill killer (not a serial killer) in which case he has no motive any sane person would recognize. If not, then his motive is presumably political, which makes this terrorism. But that doesn't mean Islamic terror, even if some people have forgotten that not all terrorism is. I would guess a homegrown wacko of a right-wing/white supremicist persuasion would be more likely.
