True, he was the leader of Al Qaeda, but it's not like that's going to stop them. It isn't like the man was the final boss of a video game and now everything is going to be hunky-dory now that he's gone. Life doesn't work that way. There are still hundreds of people wanting to rip apart our country, and now that we killed their head-honcho, they aren't going to be very happy.
Nothing good can come of this.
