In my experience it varies greatly between locations and individual cops. I don't live in a highly populated area and that certainly has an impact on my experience. I have been pulled over for nothing except being in the time and place where it was more likely to happen given a field sobriety test by a rookie county mountie that wasted everyone's time. I've also served on a grand jury in the recent past and met an awful lot of cops, DA people, witnesses and victims and heard their stories. I do my best to stay out of the way of the police and not be doing anything to get busted for.
