I believe that the overwhelming consensus of expert opinion is to get family members to safety, whether or not the bad guys are already in.
Don't think so. Who could believe that your family is safer if you allow home invaders into your home under the mistaken belief that escorting your family to safety is the first priority---knowing they'll be MUCH harder to deal with once they're in?
Your family should know how to go to safety on their own. GUARD THE DOOR! That's when Bubba and his friends are most vulnerable.
If they're already in the house, then I agree that getting them to safety is the best course.
