Why in the world can't they track down terrorists on the web? Some loser downloads kiddy pr0n or releases a virus on the web and they'll track that person 1/2 way around the world and pin it down to one computer at some apartment building. But if someone posts on the web claiming responsibility for blowing up buses or posts a video of themselves cutting off someone's head we can't seem to track that down...

If the authorities can't get past the safeguards the terrorists are using, I assume your local haxor could. Is there just some simple explaination that I'm missing? Are the terrorists really that much more tech savvy than the average guy busted for online stuff?
