Many citizens tend to walk around their home looking for the intruder. It is much easier in that case for the perpetratorto disarm someone that is holding a shotgun. (think someone walking around with the barrel out in front of them as they reach a corner)
If you are doing it right, its not a problem. You want to pie a corner or room before sticking any part of you or your weapon beyond what you can see. At any rate, get your family safe in one room, and let the police clear your residence- its a very dangerous process even for people who are working in teams and have a lot of training and experience let alone a single person with absolutely no training to do.
