In a pile up, or multi vehicle collision... several lives can be EASILY taken at once, just due to one wrecklace driver. Let alone the 2 or 3 or 4 wrecklace drivers that are involved in a chase. A serial killer usually picks off one... MAYBE two people at a time. So no... I dont agree with you. Driving wrecklace could cause far more damage. Besides... How many of these people being chased are serial killers? Probably not many... More people get chased over auto-theft, posession.. who knows? The police dont know why they're running until they're stopped. And its usually over something stupid.
Im just saying with all the technology at our fingertips... There isnt any reason why police shouldn't already be two steps ahead.
Sure, doing so means infringing on privacy.... But hell, our government seems to do a pretty good job of that as it is. If britian has technology to track people... without chasing them in hot persuit... Why don't we? (probably not in our budget, what with the war and all).
Its all politics when you really think about it.
