Of course he does. No need to be snippy. As has already been pointed out, Pope Francis is not the first Pope to be out and about the public, Pope JP11 was until he was shot and that changed how he interacted with us. We all remember how we loved that he reached out to us. And yes, I am sure that he knew what a chance he was taking as he made those very personal gestures.
It is wonderful to see Pope Francis keeping his practice of moving among the public but it is only a matter of time, I believe before he is forced to change this.
