Nothing wrong, actually, from the perspective of the groups benefiting from trade in guns and rifles, which also have tremendous sway over the congressmen and congresswomen. 

re:  "whites are superior and the rest of those colored are condemned."

    In American politics it always been and will be like this...

  The continents they were after, today's USA, Canada, Australia were all stolen from the First people...

  Nowadays 😉 uncle Sam's eagles eyes are focusing on ex UDSSR and the Middle Kingdom...

 Needless to mention, he needs all the help he can manage to do the dirty fighting for him...

Re: "Coloureds"

      Not after the people they were,  their land they were after...

  Just look at America, Canada, Australia...

 An incredible landmass indeed...

 However, 

Rather the truths I must say...

Them other weapons are being planted in the kids brain's by their education system...   How very sad.

 Unfortunately, in one of our provinces foreign agents tried the same.  However, after much struggling the baddies were eliminated and happiness returned once again...

  But like any Cancer, certain sleeping cell did remain and will be surgical removed...

US is no longer Land of the Free and Home of The Brave but land of fee and home of the pay.

Killing escalates and pushes racism into its own realms that looms a civil war. Acceleration could be heard as the brakes tear themselves and disintegrate.

No longer is US could consider itself a civilized human nation but one that whites are superior and the rest of those colored are condemned.

3 killed, 6 others injured...

  In my opinion, that lad pulled the trigger being fully aware that 9 kids could have died...

 Doubtlessly, his well paid lawyers would figure how to soften the charge...

As grand parent around the globe would agree with me, why do American kids have to kill each others in schools???

  Why, such s simple question; why is it constantly happen???

  Why don't them parents ask their own media regarding this horror instead blaming everyone else but themselves...

US social ills are far too deeply rooted. Not possible, even if gun is banned. Reason is there is other form of weapons easily available.
