ASSAULT WEAPON BAN. AGAIN.
Whether crazies, unstables, racists, angry assholes, what have you, the common thread they all have above any other is availability of assault weapons, used in every single mass shooting.
Take them away now, make them illegal, and we will be 80% further away from mass shootings that result in mass killings.
Background checks, red flag laws, and mental health treatment will further limit access to guns.
