Former Georgia Rep. Bob Barr, a man for whom I've never felt much esteem, succeeds in making me laugh.

In the case at hand involving McKinney, for example, her disdain for the police force on Capitol Hill is well-known and previously exhibited; and on a particular day in which she is harried, busy speaking on a cellphone and clearly having a bad hair day, it would be obvious that she was a time bomb waiting to explode at the nearest person wearing a badge. Pre-emptive arrest would be not only advisable, but essential to protect her, all police officers within her arm's reach, and the surrounding public. Open and shut case.
