I've also been worried that more people will do this, thus making the public transportation systems a more attractive target for terrorism. Think about it. I know you all are in a bad situation. I'm several hours away and also get concerned. However, I think we have to go about our lives b/c this person(s) changes MO's to accommodate the changes we make. Be careful, but live your life!
