The Bruce has a couple excellent posts on his blog this week. The first informs us of a TRAC report criticizing the DHS' lack of focus on terrorism. The second is an essay he wrote for Wired titled "Tactics, Targets, and Objectives" that touches on TSA, but really goes broader on the topic. The essay is very informative, I think, and definitely worth the read.
I don't have any commentary really to add. I'll be generating some new original content here over the weekend -- once I get my feet back under me from the break-neck pace of work these last couple weeks.
