This case is a powerful argument for stronger Gun Control laws in America

Why is a random 17-year old kid running around threatening crowds of people with an AR-15 style rifle?
This mentally ill White supremacist kid should never have owned a firearm, let alone one as militarily dangerous as this.
Now 2 people are dead and another person is severely injured thanks to this lunatic manchild's toting around of a deadly weapon as a toy.
Otherwise, everyone would've been still alive and doing well today! Today! Speaking with their mother and father and with their loved ones. That is so tragic unless your heart is made of stone.
Foolish policies have deadly consequences.
Too bad there are so many fools who are suckers of the weapons manufacturers of America who just increased their legion kill count.
