SJ - totally get what you're saying. i was watching CNN when i came how to catch some coverage, and they were trying their hardest to define it as a terrorist attack, and making it their best effort to call it the twin bombings. it's pathetic how everything gets associated with terrorism, but the worse of it is what they associate terrorists with.
criminal attack just sounds like someone is getting robbed or hit by a thief. it's a little larger than that.
