If the Islamicist has its terrorist, maybe the decent, law abiding members of peaceful society needs its vigilante.
Many a peaceful citizen of Western society has felt the fear of terrorism. Maybe it's time for the terrorist to fear the Western society's citizen response.
We are not sheep. We are simply outraged. If the terrorist is willing to die for its beliefs, we are willing to kill that terrorist. No one else needs to die.
I am not philosophically opposed to vigilantism. But this is dangerous talk... you know that, don't you?
