M.N.: In today's political climate this possibility of bacteriological or toxicological attacks on US presidential candidates is not a sick fantasy, it is a real danger. Attention, FBI, Secret Service and campaign managers: this circumstance has to be taken very seriously, and simple, common sense protective measures have to be introduced, to minimize the spread of infections in the large campaign crowds.
The episode with Mrs. Clinton's "pneumonia illness" has to be investigated very thoroughly, including the epidemiological analysis: what is this "bug" exactly, are there any traces of it been cultivated in a lab, how was it introduced (some reports mentioned sick staffers), who are the other people afflicted with this "bug", etc., etc..
