I'm trying to imagine why there would be a shooting on the Jerry Springer Show, of all places. From the admittedly limited number of times that I've seen it, it was pretty apparent that the guests were either fabricating their stories, or at least highly exaggerating their emotions.
For example, a young couple go on, the woman tells the man she has some news for him, the guy gets all chirpy and says "Sure, honey, whatever, you know how much I love you", and then goes into a shocked psychosis when she tells him that she wants to break up. As if anyone could go on the Springer show with his girlfriend and NOT expect her to say something bad.
And another time, he had families who get engage in food fights at home when they get angry with each other. And at the end, he sets up a big smorgashboard and asks them all to sit down, to see if they can eat in peace for once. But OMG guess what!! They all start chucking the food at each other!!!
Like, I'm sure the producers used strict journalistic methodology to ensure that these people really did have food fights at home, and weren't just amateur comedians trying to get on TV.
