I'm getting tired of the term "they need to change THE law!"

Oh go on! Exactly which one single law are you talking about? I promise you, even as gun owners ourselves we would all appreciate and agree to any one single law that would positively stop all gun violence.

A gun grab won't work.
More security won't work.
Armed teachers would cause us to lose teachers.
Raising the age to buy a gun won't work. When did you sneak your first beer? You waited til 21, right?
Harsher background checks will still leave room for something to slip through the cracks.
Stopping the production of AR-15's won't help. There are already millions out there, of which all (sans a couple) have caused no harm to anyone.
I could keep going. Please tell us this ONE Magical law that would end this crap. Please, I bet we'd find a way to make it happen.
