Who is saying mass murder is okay? Even the proponents of the Democrat proposals, much less professionals in the field, don't claim they could or would stop any mass murders. Yet, admitting that, they are willing to throw due process out the window. So much for civil rights.

You assume your premise that gun control works to reduce overall crime or homicide rates, that happens to be false. Further there is zero evidence it can work in the US. We have 40 years of research that suggests otherwise.
