What Works: If the police come to your door and ask to come in, politely say you’ve always been told never to let officers into your house unless you are in danger. They may tell you that they can just get a warrant. Again say no thank you. If you give consent to enter your home, officers may find illegal things you don’t even know are there, and evidence of crimes you don’t even know exist. And even if you invited them, you may still want to talk with them outside on the porch.
