Imagine if this had been done by a dark-skinned man with a foreign name from a "Muslim country."  Trump would probably hit the launch codes. This is home-grown terrorism of the worst sort, and most people will shrug and say, well, what can you do? The Second Amendment cannot be questioned! Really? The Constitution once said slavery was O.K., and that was changed without destroying the Republic.  The Constitution once said only male land-owners could vote. That was changed, and still the Republic stands.  The Constitution was once amended to prohibit the manufacture, sale or transportation of intoxicating beverages, then amended back again, and STILL the Country did not descend into anarchy and moral turpitude.  I think we can survive a little tweaking of the Second Amendment without undue alarm. Every other civilized country in the world seems to be doing fine without continuing to live in some fever-dream of the Wild West that never was.  America's love affair with bang-bang must end.
