When I first heard the reports of a pistolero making a long shot, stopping a mass murder and saving the life of a police officer a year ago, I knew that I would work to find the details if the possibility were offered

Taking a shot at 50 yards towards a perp is outside of the original ultimate “Self Defense” weapon premise as stated in the article.
Self defense as taught is more focused on the immediacy of reaction and the accuracy of that reaction to the imminent threat as it presents itself.
A 50-yard shot is more of a Hail Mary pass with intent. The officer was very, very fortunate that that shot was successful and that it saved the life of the officer.
But, although not impossible at all a 50-yard shot would certainly get the attention of criminals and maybe even ward them off from their attack.
