You receive a call for a domestic in progress a few blocks from where you are. You arrive at the scene and approach the front door. A woman with a bloody nose, a scratch above her eye and clear defensive wounds on her hands and forearms meets you at the door. She tells you she is all right and does not require medical attention. When you ask what happened, she invites you into the house. Once inside, you notice a male in his late teens. The knuckles on his right hand are red and swollen. You also notice he is on the floor playing with Matchbox cars while Sesame Street plays on the television in the background. The woman explains she is the boy’s mother and that he is autistic and can sometimes have violent reactions in situations where he feels he doesn’t get his way.
