Way to generalize people for what they shoot with. It is the person behind the weapon, not what the weapon looks like....
I don't read range reports, but I know what I see. The serious incidents I have witnessed all involved shooters with tacticool or at least short barreled black shotguns. As for small children being a problem, everyplace I go their parents supervise them extremely well. There is nothing wrong with generalizing if the facts support a conclusion.
BTW, while my clays gun is an o/u wearing walnut, my other 12 gauge is a black 870 express that wears a short barrel with an extended magazine around the house. Once in a while it even makes its way to the clay's club sporting a 28" field barrel.
