The lady didn't get any damages for emotional distress. She got part of her medical expenses paid. Not all. Part.
You still have to sue under a theory of why you are entitled to compensatory damages. Her theory had to have been Intentional, or maybe Negligent infliction of emotional distress. She didn't suffer a heart attack or any other physical injury. She went to the emergency room because she had anxiety, and this leads one to believe that she is saying that her emotional distress should be paid for by the teenagers. Further, no other tort works in this case. Assault, Battery, negligence, etc. It had to be IIED or NIED.
