I’m saying ‘You need to send someone to fix my lock.’ All of a sudden, there was a policeman on my porch. And I thought, ‘This is strange.’ So I went over to the front porch still holding the phone, and I said ‘Officer, can I help you?’ And he said, ‘Would you step outside onto the porch.’ And the way he said it, I knew he wasn’t canvassing for the police benevolent association. All the hairs stood up on the back of my neck, and I realized that I was in danger. And I said to him no, out of instinct. I said, ‘No, I will not.’

My lawyers later told me that that was a good move and had I walked out onto the porch he could have arrested me for breaking and entering. He said ‘I’m here to investigate a 911 call for breaking and entering into this house.’ And I said ‘That’s ridiculous because this happens to be my house. And I’m a Harvard professor.’ He says ‘Can you prove that you’re a Harvard professor?’ I said yes, I turned and closed the front door to the kitchen where I’d left my wallet, and I got out my Harvard ID and my Massachusetts driver’s license which includes my address and I handed them to him. And he’s sitting there looking at them.

Now it’s clear that he had a narrative in his head: A black man was inside someone’s house, probably a white person’s house, and this black man had broken and entered, and this black man was me.

So he’s looking at my ID, he asked me another question, which I refused to answer. And I said I want your name and your badge number because I want to file a complaint because of the way he had treated me at the front door. He didn’t say, ‘Excuse me, sir, is there a disturbance here, is this your house?’—he demanded that I step out on the porch, and I don’t think he would have done that if I was a white person.

But at that point, I realized that I was in danger. And so I said to him that I want your name, and I want your badge number and I said it repeatedly....
