Go about your business, the Media hypes all of this. I was on a business trip in St Louis a few years when similar incidents wee curing. If you watched the news it was the end of the world. Being there, nobody paid much attention to it.
If you do go and you should, practice situational awareness just in case.
Great point. Perspective,common sense and situational awareness is key. This is all very serious but media and even our side can hype. I was at a foreign airport once and it closed due to threat of bad guys wanting to blow a plane out of the sky and warned once that going into a city was a death sentence to Americans.
