Over the past week, there's been a lot of blog chatter about a tazer incident at a UCLA library that was partially captured on video. To quote James Joyner, "I agree that the use of a taser against a skinny student for the crime of being a dumbass would appear to be an excessive application of force."

The video is extremely disturbing for the cries of the tazed student, Mostafa Tabatabainejad. What I found interesting, however, was the way in which every person on that video acted according to type. The security officers acted as brutal thugs who would not have their authority questioned; the students acted as the righteously indignant chorus. Even Tabatabainejad seemed to be playing a role, the belligerent protestor ("here's your f#$%ing Patriot Act!!"). The violence is disturbing, but the characters playing their parts grounds the sequence into familiar tropes. It is, therefore, perhaps less shocking than it should be.

For me, the more discomfiting video was Michael Richards' apology on The Late Show with David Letterman for his racially profane diatribe at an LA comedy club over the weekend. Richards, a comedian, is acting in a non-comedic fashion. The audience, confused about what's going on, begins to laugh at Richards' apology. Jerry Seinfeld, a comedian, tut-tuts the audience for laughing. Richards, who on Seinfeld played a character who seemingly fell ass-backwards into success, has put himself into the exact opposite situation, someone who seems completely mystified about how he wound up in his current predicament.
