Satoisfy the bizaare bloodlust of those advocating a daily screening of the 911 atrocity on every station identification.
Desensitize everyone else who doesn't have that strange fixation.
I dont think what you advocate will make 911 more meaningful to most people. As I said, it will make it less real.
Doesn't matter - they've already forgotten. Had we kept playing it (hourly, daily, at the start of each day, etc) they might accept the images as real. However, we didn't, so now they would think it was some kind of Hollywood production.
Shalom.
