Bitsy Brennan’s son Edward Brennan was the first person to attack Johnny. The guy around 6 feet tall and heavy body weight stood beside his mother during the entire scene. 

He used dirty words and strictly mentioned “black” for Johnny, which got captured in the video that Johnny was shooting. They went upwards without waiting for the cops to come.

Likewise, his mother, being in the financial administrator position, was pretty sure about her son not being arrested.
