An accidental discharge( to me)is the firearm malfunctioning.
In my opinion if it's in the shooter's hand it is almost never, ever an AD. This has nothing to do with legalistic terminology. It has to do with responsibility...or rather trying to dodge responsibility.
This is precisely why I hate "politically correct" terms.
