A black man is approaching my door and ringing the bell. What should I do?

If a stranger is at your door, you should ask who is there and tell them to identify themselves. You should also make sure that your home is secure, and ask the person to wait outside while you inspect the entrance. If you recognize the person, you can let them in and start a conversation.
