When I ignore the terrorist no matter what they do, I am trying to reset peoples brains--it usually doesn't last long. I am not advocating it, I am just saying, what if you ignored him--would he be able to get followers? Would he be able to get funding? WOuld he be gratified by his actions? Would he be able to manipulate?
In actuality I am all for killing them, but only as a finger of a far greater reaching plan
