I was responding to the claim that a firearm is no more dangerous than a wrench or screwdriver. Apparently, it's been long standing conventional wisdom that firearms are more dangerous than wrenches or screwdrivers at airports and on planes, whether within the passenger cabin or not; and it's why some weapons and dual-use items have more restrictions than others applied to them at airports and on planes. We do recall that firearm transport on common carriers, whether in the passenger cabin or in checked luggage, is more regulated than the transport of wrenches, right? And it has been this way even decades before there was a TSA.
