I'd like to see a plan for removing all the illegally owned guns from US cities. I rarely see anybody talk about how to get those off the streets. Those guns are already illegal and nobody is doing anything about it, nothing that is making a dent in the problem anyway. The murders and shootings continue just as they have for decades, accounting for the majority of US murders by gun. Half of the major US cities are war zones because of illegal hand guns, and it has nothing to do with the mentally ill and mass shootings.
And yes, we should still deal with the mental illness issue around gun access and ownership simultaneously.
Walking around SF, I (a regular looking guy) have been accosted multiple times. Its legitimately frightening, and would be so much worse if I was elderly or disabled or otherwise unable to defend myself.
