Shooter on MIT campus

So the shooter was the first suspect of the Boston Marathon bombing, and was killed during the gunfight. Now Watertown and the surrounding towns are on lockdown because of a manhunt for the second suspect, who is the brother of the killed suspect. They're supposedly from Chechnya, and they somehow managed to get into the US last year - nobody seems to know how they got in, whether it was legal or illegally.

Now I've got people flailing that this is a sign the world is ending. ==
