There was a similar incident in Houston last week. Fortunately the victim lived, unfortunately his future baseball career is probably over.
It appears the cop figured a black kid in a rich neighborhood must be up to no good and probably driving a stolen car. I guess the cop never figured he could be the son of a retired professional baseball player
His mother and father witnessed the shooting in their driveway.
