There is a real difference between an accidental and a neglegent discharge.I reread the post, no need to cuss or bang your head on a wall.
You call it a politically correct "negligent discharge" I call it an "accidental discharge", same-same whatever you wish to call it.
All the other ADs that occured involved somebody stupidly pulling the trigger at an inappropriate time because firearms don't generally go off for no apparent reason and playing nomenclature games doesn't change the fact that accidents are caused by negligence.
There are true accidental discharges. For instance - the firing pin jaming in a forward position and every round after the first slam fires turning your nice, safe 1911 into a class III weapon.
If your finger is on the trigger when it shouldn't be, and the gun goes off, it's an ND, not an AD. If it's not caused by the gun or other equipment breaking or behaving in a fashion nobody would have predicted, it's neglegent.
You can rail against nomenclature all you like - but the way we use terms is the way we use terms. Up is up, and down is down. It has nothing at all to do with being politically correct. It has to do with using common terms the same way others do.
