The U.S.'s ridiculous obsession with "Why?" Every mass shooting or any murder for that matter all anyone cares about was why they did it. I've posted on this before but it bears repeating. There is a specific jury instruction that the prosecution DOES NOT NEED TO PROVE MOTIVE. You can have a whole murder trial and get a conviction and the why never comes up. The constant "why?" is a way for gun legislation deniers to deflect from the real problem. Is there an acceptable answer for why? They were mentally ill so we need more mental health treatment. They were bullied so we need to focus on stopping bullying. They were embarrassed that white people owned slaves so we must ban critical race theory. Any possible thing to ban except the cause of the problem. The death certificate lists the cause as death as "gun shot wound." THAT is the only why that matters.
The NRA and gun owners like to ask "why" so they can circumvent laws to limit the ownership of guns, mostly machine guns. They will always blame it on people that aren't in their circle of friends. Their why has a totally different answer than the mainstream public's why. They don't give 2 shits about the answer as long as they lure the public from the right reasons. It will always be OUR problem not THEIR problem.
This is true. The whys do matter, in the long run, but in the meantime, what's much more important is limiting the killing power of the mass shooters, by passing sane, effective gun control laws to limit their access to automatic weapons of military grade firearms, so that even if they do kill, they can't kill near as many in a single attack. But the mass shooters never target or kill members of the ruling class, who are so well-protected anyway, that they can't be killed by a single lone gunman, and thus the political class and their rich donors, feel no threat and are perfectly content to let the lower classes continue to kill each other thru mass shootings. If we suddenly saw any mass shootings targeted at and killing any members of the political class, their rich donors, or the children of those two groups, you'd be amazed how quickly we would see radical gun control laws passed.
You have not mentioned "greed". The greedy will justify their actions to protect their profits by any means possible. They will continue to have support as long as they can grease palms.
Sandyhook did not make an impression on the right-wing MAGAt gun nuts. Nor did Uvalde. Why should this latest unpleasantness? They have bigger fish to fry (i.e. turning the USA into a white supremacist, theocratic dictatorship).
