I see this as a potential problem with an exposed hammer on a carry gun. If you're close-in (like many self defense situations seem to be), it's an element of luck for the bad guy that I'd rather not give them. For the lucky cops, it saved their lives. If the role is reversed, the bad guy would be lucky and you'd be in an even stickier situation.
I've heard of this before, only it was the "flap" of skin between the thumb and pointer finger that the cop got lucky with (basically making an "L" with their hand and wedging it in front of the hammer).
