Hot pursuit

Imagine you're a police officer, out on patrol, and you see a car speed past. You're sure (you check) that it's stolen. What do you do? Do you set off in pursuit, at speed? Or arrange for an intercept down the road- by helicopter, or other squad cars? And if you chose to go in pursuit, do you do so with sirens blazing? And would your decision be influenced by your location - city or country? Would you be worried about the possibility of "collateral damage" to innocent bystanders, those involved in the chase, property. Is there a better way to apprehend these wrongdoers?
