“Gun violence” ends instantly when Human Violence ends. So far, I have not heard a single gun control advocate call for working to end human violence. The same people who are quick to say not to blame all Muslims or Blacks for terror or crime are equally quick to blame all law abiding gun owners when someone commits an act like these mass killings.
The Promise Program in Broward County, Florida (and elsewhere ?) replaced the Rule of Law.
The point of the Promise Program was to not arrest criminals of the protected class (if Barry had a son) , so as to increase federal money and thereby higher salaries to bureaucrats.
