all the factors...among them...
>Make it extremely difficult to own an Assault Rifle...btw, the more I look into this, the more I realize that even soldiers are trained to use the "semiautomatic" setting in combat...not full-auto...which underscores why such weapons deserve the title...also restrict high capacity magazines...high velocity ammunition, etc. (see NY's "SAFE ACT")
>Institute rigid background checks...longer waiting periods..."Red Flag" communications...databases, etc.
>Fund school counselors trained to recognize dangerous behaviors in students...give them the means and authority to refer such students to qualified mental health professionals.
