The incident makes no case for point shooting, to answer your question.
Sounds like the thugs fled when some shots were fired in their general direction by a brave individual who was operating on adrenalin.
after receiving a possible fatal wound.
His heart, and the thugs' lack there of, is what turned the tide, even though his return fire probably didn't rise to the level of "point shooting".
Hard to make a case for a method of shooting that resulted in no bullet holes in the adversaries. The lesson is keep fighting and don't give up.
