Philip,
I respectfully disagree. I think you underestimate the power of
video, and the power of a 24/7 global media culture to disseminate
such broadcasts in a way that ensures that we are never free of
them again. In this age of file sharing and homemade filmmaking,
clips of Cho are no doubt already being edited into loops for the
productions of other malcontents whose names we do not yet know.
Yes, Cho would have gotten publicity without the video, but it
wouldn't have been on his terms; his elaborate broadcast allows him
to dictate those terms to significant degree.
From the parts of the video I saw (yes, I watched it, too),
Cho's rants are breathtakingly narcissistic, self pitying, and
grandiose - right out of Psych 101 under the God complex, complete
with references to Christ. Cho's broadcast may not be the impetus
for others to commit mass murder who otherwise would not have, but
it does offer them a significant solace in debating whether to go
through with it: a promise of a kind of eternal life in the media
age, a promise that they will at last be listened to. That seems
like too much positive reinforcement to me.
p.s. I don't think you would be hypocritical to watch the video
while also criticizing NBC for airing it. You and I do not control
their broadcasting decisions, but we do have to live with them.
