Does that have any value beyond reinforcing people&#x27;s irrational fear of mass deaths? What if you let your family know you&#x27;re not one of the 100 killed in this attack then die as one of the 600 murdered in France each year by common crime?<p>I saw this happen with the London bombings. A colleague was almost in tears because her son lived in London and she couldn&#x27;t contact him on the phone. It turned out he was fine, as approximately everybody else in the city was too.
