Civil Wars already happening. It doesn't have to be large groups of people meeting at Bull Run wearing fancy uniforms. I could be subversive activity done on the sly. Anything done to thwart your opponents ability to carry out his plans. Anything.

I've got my list already made. Addresses and everything. Including 2nd homes, 3rd homes and known associates/vacation getaways. God I love the internet.
