I didn't really appreciate the description to be honest, nor did I request it.
Those with a morbid fascination for guns might feel this is some natural born killers Hollywood inspired death, I think the reality it will be very different. It does not take into consideration the person having to do the shooting either.

There are different levels of unconsciousness though, someone can appear completely unresponsive but actually be semi aware (able to experience pain but "out of it") or even completely aware (pain, sound, clear thought). Some coma patients are able to recount entire conversations that were had around them when medical staff thought they were not conscious.

Anesthesiology is an entire medical discipline, it is very very complex. The only way they could more or less ensure that it's done correctly would be to have it carried out by a trained anaesthetist, and I don't think many are particularly keen to train for years in a delicate area to learn how to not kill people... And then start a career doing the opposite. Even then, there are plenty of documented cases of patients being aware, but paralysed, during surgery. It's also thought that it might even be more common than is reported - some patients might be aware at times during their surgery but subconsciously "blocking" the traumatic memory.
