I RARELY answer the door unless I am expecting someone. Not to say I don't check to see who is out there when someone does come a knocking. But like I tell my wife and kids . . . IF it is someone we know (a friendly) then they have our phone numbers and can give us a call ahead of time or call us if we don't answer the door. My friends and family know not to "pop in" without calling. Time to time, I will open the door for a neighbor I know very well, but that is the only time. I won't even answer the door for people who appear to be PD or whatever. If it is an emergency they can break the door down. I will of course have already called 911 to verify they are real/legit and have a pistol/rifle ready in case they are not on the up and up.

You can not be too careful. Especially with your family.
