Deaths from towballs

[AB]

What about those "Recovery Hitch tongue with shackle" type things that go into where your tow ball tongue goes and uses the pin to hold it in place? are these just as dangerous? Is it the "Pin" that is letting go or or ball snapping off the tongue?

In most cases the ball just shears off from the thread and flies towards the vehicle being recovered like a cannonball.

Way too many people get injured and many deaths are caused by this.
