No I'm not.

I think everyone who has a reasonable right to self-defence has a reasonable right to put their own life > *. I don't restrict that just to the Police.

If a mistake is made then I have supported sacking the officer concerned if on a balance of probabilities (civil level) they should have known it was clearly a bad shoot at the time - and prosecuting them for murder if beyond a reasonable doubt (criminal level) they did know it was a bad shoot at the time.

I just don't support abolishing the strict bar on proving beyond a reasonable doubt that applies at a criminal level.
