What is meant by "He's got his own label"?
While it sounds as if the shooter will not be charged, there are a lot of concerns about what happened when she fired those shots. The cited article noted that cars in the parking lot were hit. Using cars in the parking lot may not be the best choice of backstop.
The article is too vague for rational discussion of the appropriateness of the shooting - "She said she came out of the restroom and saw my brother on the floor. That's when she started doing what she gotta do" just does not tell enough about the threat level.
