They may even think they are being “responsible” by not publicizing such events, lest they encourage others to commit what they regard as reckless copycat acts. But by omitting the fact that the good guys were armed, they risk conveying that it’s somehow safer to “tackle” an armed killer with one’s bare hands.
This journalistic bias against defensive gun use was especially clear in a 2009 example cited by Cramer and Burnett, when a robber held up a small grocery store at gunpoint, emptied the cash register, then herded the customers into the back room. The store manager “opened fire on the robber, killing him.” The police ruled it “justifiable homicide.” But the Miami New Times reported it as: “South Florida Store Clerks Go Vigilante.”
It’s hackery not to tell the whole story. Propagandists should not hold themselves out as journalists.
