b.t.w. firemen/women are often involved with fire investigations AFTER they have put the fire out...interviewed, called as witnesses (etc). Why? They are on scene...paying attention to the details to help them combat the fire. So in that sense, the investigation into what started the fire, what the conditions where, etc. are already occuring DURING the putting out of the fire. In other words, they too can multi-task. Walk/chew gum, Investigate the NBC issue/fight for other conservative issues, etc.
I'll give you the benefit of the doubt and assume that you, yourself, are not restricted to being single threaded. Why would you assume those who seek answers regarding Barry's eligibilty are? Do you have a superiority complex?
