The girl was transgender, supposedly transitioning to be a boy, and they say he was bullied in school. The boy shooter is just another kid with a mental problem, having demonic signs, 666 and F___ society spray painted on his car. Both kids were armed with nothing more than pistols is what I heard reported.
Once again, the shooting takes place in a gun-free zone, only ones with the guns were the killers.
Once again there was no security guard or officer in the school or on the property who could have stopped the killing and attack.
Once again, there were no adults in the school who were experienced and legally permitted to use a firearm, no staff allowed on property with concealed carry permits who could have stopped a young boy and his friend who were attacking with nothing more than a hand gun.
Once again everyone sits back in wonder at how this horrible thing could happen.
Without security changes in these schools and other gun-free zones, lets just wait for the next one to happen and all be shocked again. Maybe some day when people wise up, the killer will be dead instead of the innocent victim.
Rest in peace to the young boy whose life was taken, sympathy to his family who are now mourning the loss of their son.

I have nothing further to say.
