Alright, all we know is there were two deaths, and more than 100 were injured. The mind behind the attack is not yet known, so keep your conspiracy theories to yourselves. I hate that so many people are going to use this to support their political beliefs.
Check the news. That's really the only reliable source right now. The scary thing is, yesterday while I was shopping, the mall got evacuated because of a bomb threat. I live in Pennsylvania, so I don't think there's any connection, but there could very well be.
