I fail to see your point with that video.....
A pick up truck was invented to serve duty on a farm......I'm sure the inventor was never warned that this vehicle could be used as a weapon nor did it probably ever cross his mind...
The first firearm was invented to kill....period...
Where is the comparison?
If you watch the video, the cop drove through the crowd himself while in pursuit...if he had struck and killed a few pedestrians in his quest to stop the pick up struck would he have been given a raise or a prison term?
