Are you sure about that?
They interviewed an eye-witness, a 40-ish caucasion professional woman who had been in the 2nd story of a building less than 30 meters away.
She had a direct line of sight and gave that account; I was amazed.
The responders stopped the car, extracted the child and afterwards opened fire, killing the driver.
The woman said that when she heard the firing begin she could not see the position of the hands of the person being shot.
