I interpreted Donjuanme’s comment as sarcastic, where “no way a background check would’ve stopped this” implied that they thought a background check wasn’t performed, but if it would’ve been, this murder wouldn’t have happened.
Not everyone who commits a violent crime with a gun has a previous record of doing that, or other indicators that would fail a background check for that matter. Not a lot of anti-gunners seem to remember that though, which is partly why I interpreted the comment that way.
America takes awful care of its citizens, some other countries certainly do better. I wish we’d focus more on addressing the root cause issues that push people to commit violence instead of superficial actions like banning weapons, though. Even if all guns disappeared overnight, the conditions that incentivize violence would still be around.
