“One of autism’s defining features is the inability to process even the most mundane social interactions. When police are involved, an autistic person’s anxiety level is likely to spike, triggering unnerving mannerisms or behaviors. The person may say nothing at all, appearing to ignore an officer’s commands. Or he may repeat back what somebody says to him, a form of communication medically known as echolalia. “You can imagine if a police officer comes up and says, ‘What’s your name?’ and the kid’s response is, ‘What’s your name?’ the police will figure he’s a smart aleck or he’s on drugs,” says Grossman. “Usually, the situation goes downhill from there.”
