Not unless you had Parkinsons.
Is it possible to stab someone "Accidentally" 80 times? I know you can stab them 80 times. But "Accidentally"?
I think not ! I underwent extensive training in hand to hand and knife fighting techniques and we were taught that it only takes one strike to do the job. Stabbing someone that many times is pure stupidity or a real sick person.
No freakin' way!!!!!
It is beyond impossible.
You can stab someone accidentally. You can stab someone in maximum of eighty times. But you can not put "accident" and "80" in the same route.
The only theory i can think of for the claim of those sisters is when you become under pressure and you attend to be out of control after one or few stabs due releasing the pressure and the anger. Sometimes that's how you feel to do and sometimes you become blind and off during stabbing period and the system is working on it's own automatically. But even in that case! Still we can not call it an accident.
Sure. Kinda like the guy I read about oncve who committed suicide by sghooting himnself in the back three times with a rifgle.
I suppose if you were holding a knife and were off balance and fell forward and stabbed someone and immediately jumped back up to the off balance position and suffered immediately from amnesia and fell forward again, you could.
I wouldn't try to sell that to a jury, however.
