By their own department's rules of engagement what they DON'T do, is fire their weapons at the receding target.So, a 17-year-old with little driving experience steals a car and then attempts to run down a couple of plain-clothed cops. Hmmm, what happens next? Do the cops use force to stop him or do they smile, wave, and hope the next two people in the driver's path are sharp enough to jump out of the way?
