Interesting discussion from this fourm:

Think racking a 12 gauge pump will scare the bad guy away?
I agree with this fellow:

Yes, if they break into your house with the sole intent on killing you, then perhaps the sound of a pump shotgun won't deter them.
However, given that most home break-ins are thieves looking for an easy steal, the sound of an armed and pissed off homeowner is likely to deter most home invaders.
The idea that your average B&E has nerves of steel and is looking for a fight is naive at best.
Most are cowards and will behave accordingly.
For the ones who aren't....as many have said here, it's going to be a bad day either way.
As you don't fire a warning shot, the sound of the pump serves as notice that they have one small chance to rethink their decision to enter your home.
And personally, I'd rather deter them without having to clean them out of the carpet and drywall if I'm at all able.
