Everyone keeps on talking about the imaginary benefits of "racking the slide" to frighten a potential home invader. If your shotgun doesnt't have a round chambered before the fight starts, you're already behind.
Guess what? You don't need to "warn" goblins about the danger of being shot in another man's castle. Criminals already accept that job-related danger.
If the scumbag is armed, he'll turn around a shoot you before you can bring your shotgun to your shoulder. With the shotgun aimed at center-mass, you can optionally command the criminal to leave, lay down, or whatever...but you don't have a moral responsibility to telegraph your actions beforehand.
No flame intended, but there tends to be quite a bit of misinformation distributed online about shotgun technique.
