remember how it's done in the movie "Sin City" ? ...
you take away his weapon .... both of them ..... 
come to think of it, we probably should castrate the terrorist
first before shooting him too eh ......
lol, the point about castration is to let the castrated live the
shame wat. if you're going to kill him, it's like pointless.
i was thinking shoot the terrorists, so that the world will be a
safer place.
then castrate the paedophile by smashing his balls with the
empty gun. lol
