Booth's mistress, Ella Starr, and other "unknown" Booth ladies!

A political assassin acts as judge, jury and executioner when he or(she) subverts the will of the people by destroying the person they have elected to lead them. A political assassination impacts history in a very serious-occasionally-devastating way.

Mass murderers/terrorists like Brown and Quantrell destroy more lives but affect the destinies of nations only rarely, although one could argue that John Brown's crimes did trigger events that influenced history.

Excellent point, Toia, and I will concede it. However, it still doesn't change my mind as to what constitutes a "crazy" act as opposed to an act of war. I see Booth driven by motive, not by demons.
