Its a double edge sword. If we don't answer then they think we are not home and then they can bust down our door but if we answer, we put ourself in danger. A home during Christmas break was broke into because after the creep knocked and no one answered, he kicked in the door to find 2 kids home alone watching tv who were told not to answer the door. I think we should at least yell at them NO SOLICITING GO AWAY so they don;t kick in the door.

That is exactly what the police told me when I experienced an attempted robbery while I was at home during Christmas break 2008 ~ At least yell at them through the door that you are not interested and tell them to go away!
I was just getting up out of bed early one morning and heard a pounding at my door. When I finally got up and to the front door...the two young black males were already at my front door with a crowbar trying to get through the front door. Get an alarm...and a hand gun....it's the best deterrent unfortunately!
