SRS Impacting Your Day to Day Security Concerne

After listening to some of his shows with people familiar with National security I am reconsidering family security and travel plans for the next 6 - 12 months. I don't consider myself a paranoid person usually so am I over reacting? Are these threats legitimate? I mean suicide vests that can't be detected in an airport - that's pretty damn alarming.

I am not saying we are going to stay in a bunker but I am reconsidering air travel and also going into any major cities for the time being.

Thoughts?
