also, AFAIK Sadr and the Mahdi have not really killed all that many civilians. They are more or less restricted to fighting US soldiers and Iraqi polce, which means you can't label them terrorists. However, to the average Joe who watched CNN, anyone who opposes America is a terrorist, regardless of what the word actually means. This term has been so overused and misused, thats its lost all its weight.
Europol has recently stated that anarchist groups and terrorists or "pre terrorists" and ought to be watched with extra vigilance.
...seriously, pre-terrorists, they actually used that term. I guess we've got about 6 billion pre-terrorists running around right now, I'de say thats a pretty big security crisis, wouldn't you?
