SORRY! She forfeit any right to “her social justice beliefs” the moment she chased after them and tried to stop them getting herself caught in the car door. She obviously felt they should be caught and pay for their crimes. To that I AGREE whole heartedly. Let the system do it’s work.
That's a perfectly good explanation. Or maybe she was just extremely angry. She's no longer around to clarify her motive, but she could have let her assailants get away free, and she CHOSE not to do that. Her so-called "friends" should remember that.
They should also remember that she was a successful capitalist entrepreneur, however offensive those "friends" may find that.
