I have not read of such a case, but it would be interesting. If you know of one, please give us the link.

That does not represent my opinion so knock off the flames.

In most states, the official "LEO" position is that mere "civilians" should curl up in a fetal position, let the bad guys murder, rape, and rob them, then call the skilled trained professionals (hah!) to take a report.
And you don't seem to know what "flames" are ...
