Judging by the tractor trailer driver's facial expressions and focus, it was an intentional act. He showed no emotion of the fear of impact, nor tried anything to reduce the impact such as looking for an out, blowing his horn, or any such normal reaction that an innocent person would have had. In addition, he stared straight into the camera with no remorse whatsoever. These sick people adorn their heads because they consider themselves some type of religious pious and of an elite character yet he showed no emotion even after taking 3 lives. Find out who those people were and their opposition to the DS, it is there as this is a pattern.
