The police do not always run with lights and siren. Sometimes they run to catch up to someone unawares to to repond to a silent alarm. They must however drive safe and prudent.
Doc's right, you won't win that fight. The dispatcher hears that complaint often, daily actually. And usually from someone who just got a citation.
Let it go.
And for goodness sake, keep an eye on the rear view mirror. Sometimes, the car coming up fast on your @ss isn't a competent policeman, but a crazy fool in a Crossfire.
I have seen a lot of them drive. Trust me, those guys are dangerous!
