We already have tons of statutes for all sorts of assault/battery with modifiers if they are done using lethal weapons.
Police have already been demanding that "hate crime" laws (which are historically limited to who you are, not your profession or your choices) be amended for extra harsh punishment for attacks on police officers (despite many other existing statutes with similar purposes).
In the end, prosecutions of police with harsher statutes don't matter unless the conviction rate goes up. Right now, convictions of officers for actions done while in uniform are astronomically low. We need to work the other parts of the problem (gathering evidence, getting police to stand witness against other police, getting DAs to actually charge and push for convictions, firing of officers for conduct unbecoming an officer, etc).
What do you _mean_ that's not included in the parent post? What else do you think the parent is saying if not exactly that?

I didn't name check it, but if you check my post history there's a reason I didn't call for an outright repeal of QI -- I don't yet know what the effect of that would be or what measures might replace it.
I'm all for removing QI (and outlawing indemnification of LEOs in employment contracts) and replacing QI with something like professional insurance, but from my understanding the problem isn't that "QI prevents cases from being brought to court", but that DAs don't actually bring cases to court which could beat the QI standard.
Also, in my understanding, QI is simply protection against civil actions, not criminal prosecution. To repeat - I think the core problem is more that DAs don't bring the cases, not that the law is insurmountably high.
