He did nothing wrong. >> We'll figure that out. You come over here by the car while we're talking to him. >> No, you're taking him from my house. I understand you're taking him. No, you're taking him from his house. He is autistic. Get him out of the cuffs. >> I understand that. >> Then what are you doing? >> or hurt right now? No. He's simply in handcuffs. >> I know how tight y'all put them on. >> Ow. >> Give us a little bit. >> Get him out of the cuffs and get him back to my house. He says this is his house. He just got here from North Carolina last night. He's looking at his new house. He's going to need some medical attention. You see the blood coming off his back? >> When authority crosses the line, every word on record becomes the evidence.
