I hope this bit of whether it matters whether the perps where of the Left or Right, non political, Christian, Muslim or atheist, or none of the above, is out of everyone's system. There are nutters out there from all stripes, and to make something out of what the nutter(s) believed as opposed to what was done, simply serves no useful purpose that I can think of.
And I say nutter deliberately. No cause can be furthered by this sort of act. It can only be hurt. Most of the planet recoils from the slaughter of the totally innocent. It requires a psychotic mind to go where the perp(s) went here.
I don't appreciate the mud-slinging at my mayor.
