I feel sorry for the mothers and families of Chicago (and everywhere) whose lives are marred by this violence. But I doubt the guns involved were purchased legally, or the perpetrators have any fear of repercussions from using them illegally. More needs to change in the culture of these neighborhoods - wherever they are - than any law will fix, no matter how far-reaching and specific. Serious, long-term work needs to be done addressing the causes of the violence, which is more to the heart of the matter than the guns by which it gets expressed.
I do think we also need to address the mental health aspect of this, in most "school shootings" cases that make the news, there were red flags raised about the mental health of the eventual shooter, but because of patient privacy laws, nothing was done. But targeting the weapons themselves is far simpler and politically more newsworthy than addressing that difficult, complex, legally and ethically difficult issue of mental health.
