I had a dog that stole the elastic netting from a pork roast out of the trash. It got stuck, and caused him near fatal constipation. At the time I didn't have enough money for $3000 surgery, so the vet said that as long as his gums were pink he was doing well and that I should feed him all the Vaseline I could force into him, and give him an enema every few hours. After five hours, and 3 enemas he ran for the door, he hunched over, and gave birth to a greasy black lump about the size of a softball.
We don't know how many more would have been killed in an enclosed area with an active shooter had another person with a gun not been there, and we will never know how many people have been saved because a good guy with a gun was on scene. One thing we can count on, is most of the time the news wont tell you about it!
