"Run and Gun" Fantasy or Practical?

An AR is a horrible option in a home invasion situation unless you live alone and miles out in the country.

Sure, you may kill the bad guys but you may also kill your kids in the next room, the old lady out walking her dog, or the neighbor watching TV and drinking a beer on his couch.

Spending time in prison for manslaughter (self-defense doesn't apply if a stray bullet hits an unintended target) would suck.

I can cover my entire house with a shotgun or 2. In a different situation, like out in the field, another gun may be more appropriate.
