When they are chasing someone that refuses to pull over, why are there 10 or more cars following it? Depending on the area, that is probably 95% of the entire workforce chasing one car. Two or three I can understand but it's comical to use all those resources for one person

Most agencies have policies on how many can be in a pursuit running code (lights and sirens) and it's usually around 3. That is if they can even pursue because a lot of agencies have a do not pursue policy. You you believe you're seeing 10 plus in a pursuit id actually be pretty shocked if it truly was that number. If it is they are crossing multi jurisdictions.

Too many viewings of The Blues Brothers.
