Attorney General Alberto Gonzales admits that:
1.) Hundreds possibly even thousands of American citizens may have been spied upon since Bush authorized domestic spy program.
2.) These powers to break the Federal Intelligence Surveillance Act (FISA) came with the Congressional approval for Military action in Afghanistan, and that spying is simply a incidental action of war.
Put these two together and we can conclude the Bush administration has accepted the reality they are at war with American citizens. If spying is an act that can be done to enemies in at time of war, then spying on Americans is an act of civil war.
