someone's knocking

Two recent tragic shootings underscore the importance of protecting yourself when answering the door. If someone unexpected comes to your door, do not open the door. Instead, request identification and the reason for the visit. Also, don't stand directly in front of the door. This will protect you from someone shooting through the door or kicking it in. For added security, take your cell phone with you when you respond to someone at the door. If you need to call 911, you won't have to search for the phone. Finally, if your door has large windows or glass panels, consider installing an intercom system so that you can communicate with people who are standing outside your door without placing yourself at risk of assault or home invasion.
