I think a more appropriate question is where do you start? But I'll answer anyway. A domestic terrorist will undoubtedly be tried in a court of law by a jury of his peers. Personally, I'd shoot the bastard on sight but president Bush won't.
The POTUS and everyone who has worn the uniform has sworn to protect this nation from its enemies both foreign and domestic. Domestic terrorists are also treasonous bastards and should be dealt with even more harshly than the Al Quaeda scum.
