re: Cops passing you going way over speed limit

There are certain reasons you can see a cop speeding and/or putting on lights to get to a call, without having lights and sirens blasting.

1- they could be responding to something that they do not want to alarm the suspect they are coming.

2- they might be going to a call that requires a quick response, but doesn't warrant having lights and sirens

3- people absolutely lose their minds when a cop car is behind them with sirens. It actually creates a more dangerous situation in a lot of cases.
