I mean, yes, but still fuck AI. It's totally possible that this person may have done the same thing had they been in a different head space that day.
Also the analogy doesn't make sense. AOC is not saying "hey mass shooter have a bulletproof vest." she's saying "hey officer, why don't you take away that mass shooter's gun instead of their bulletproof vest?"
As far as I know, the ability to change the colour of the obnect your cursor is hovering over is not a thing you can do in windows.
