If Bush is serious about this war on terrorism, he should come down on this kind of thing and come down as hard as it needs to be, because it is a form of terrorism.

The people who are doing this are carrying on the work of the Tuesday's terrorists, however unwittingly.

Nobody knows for sure yet where the people who planned Tuesday's attack, so it's right they should wait until they are sure. But the authorities surely know where the people who are doing this kind of thing are, and they need to go after them.
