Democrats waste NO tragedy, and that includes Las Vegas.  If you want to look at Chicago, Baltimore and other large cities, it becomes immediately apparent that strict gun control does not prevent high violent crime rates.  Many shootings occur in gun-free zones, yet we keep making more of them.  It is much easier to blame guns and vilify gun owners than actually address root causes of violent gun crimes.  The ultimate Democrat strategies lead to armed police, military and criminals, and ordinary Americans defenseless.  NOT good in a constitutional republic.
