Take their assault weapons!
Give them some more range time so they can hit what they aim at. That is true gun control.
"Assault weapon" and "assault rifle" are leftist propaganda terms intended to convey the danger of attack.
An assault weapon, properly defined is a short barreled rifle capable of selective fire. I strongly suspect that that the weapon used in this case was just a semi-automatic carbine.
We should use the term "semi-automatic carbine" in all communications with politicians and the press unless we are talking about selective fire weapons or "semi-automatic rifles" like the M1A or FAL, which the leftists often mistakenly call "assault weapons" as well.
