"When will our elected officials stop the slaughter of the children, women and men of this country?"
There are already statutes at all levels of governments around the world making  the unjustified killing of a human being a punishable offense. There's not much that can be done that doesn't infringe on the right to self defense and that right, in this country, includes self defense with a firearm.
If you care to look, you'll find that a more fundamental problem is that despite laws, people continue to kill other people with whatever is handy be it firearms, knives, grenades, ropes, explosives, poison, rocks...you name it.
As to being terrorized, speak for yourself rather than the whole country. I'm not terrified.
