It's a tragedy that five years after Virginia Tech so little has changed. How many years must we wait until tragic headlines about school shootings, children dying, and people using the "shoot first and ask questions later" defense to take the law into their own hands go away? When will we finally get the courage to stand up as a nation and say enough to the deadly proliferation of guns and gun violence that endanger children's and public safety? As a nation we can't afford to keep waiting for common-sense gun control laws that would protect our children and all of us from indefensible gun violence. The time to act is now.
