Let's think this through logically: Edward is a fictional character. As such, we can kill him with fictional means. After the last movie comes out, we're done with him and there's nothing more to worry about. The SOPA Director is a politician. Politicians survive on support from the public. If the public hates his ideas, he won't be reelected and he won't be able to push SOPA at all any more.
Beiber, however, is a (somehow) popular celebrity. You can't petition him to stop. So long as he's popular he'll keep going. You shoot him, he can't be popular any more. Problem solved.
Bieber is totally fine and not worth killing. I've never been FORCED to listen to Justin Bieber, so let him do what he wants. The SOPA Director came out against SOPA the week of the blackouts, too. That really just leaves Edward...assuming we don't actually mean the actor, yeah, all right.
How about pick up the gun, line the mother fuckers up in a straight line and shoot them all? Trust me, the bullet will go through all three of their heads, as there is nothing to stop or slow down the bullet up there.
