So, was this a failure of law enforcement? Santiago does focus our attention on one primary issue: possession of firearms by people with mental health concerns. It is time for gun rights advocates to acknowledge that reasonable restrictions on gun ownership actually protects the Second Amendment right, rather than dilutes it. Mental health professionals have yet to agree to the criteria sufficient to deny a constitutional right. And even if agreement is reached, enforcement would require a coordination between law enforcement and mental health professionals in a way that has never happened before.
