Watched your story on "Red Flag" laws on Colorado.
I'm a resident, and firearms owner.
One of those you interviewed mentioned "responsibility"
If the CBI (Colorado Bureau of Investigation) has adverse mental health information on record, no legal sale should occur.
When purchasing a firearm from a licensed dealer, you have to complete a background check.
This form asks whether the purchaser either:
has ever been adjudicated a mental defective or committed to a mental institution
is subject to a protective order restraining the person from harassing, stalking, or threatening his/her child or an intimate partner or child of such a partner
renounced U.S. citizenship
is under indictment for a felony
is an illegal alien. I'm surprised you did not report on background check requirements
If families know a person has mental issues, they should ensure the CBI has that info
