Again, whoever is doing the killing, there are far too many of them in the USA. And you won't even try to address the main reason for this, the easy availability of firearms to all your population which will, of necessity, include white supremacists, people of colour, political factions, heck even people just having one bad day. I don't care what colour or what political viewpoint a shooter takes, I would just like efforts made to stop it before more innocents like school kids get killed by anyone of any background.
Sadly there is an entire political wing of this country who feels that the occasional school-child massacre is an acceptable trade for a protected right to own and use firearms.
That isn't a strawman or a pejorative extrapolation, by the way; not some "so then you must think..." gotcha. Many of them will explicitly concede that while they don't really like to hear it framed that way, it is true.
