I have had to deal with a dozen or so cops a dozen or so times over the past 30 or so years. Traffic cops, beat cops, detectives, ... never has the experience been less than "good." I can think of one time when a particularly young state trooper might have been looking to put a notch on his belt. But, even if it was only by 5 MPH, there's no doubt that I was in fact over the limit.
In the past decade or so, if I've been stopped (e.g. for rolling thru a stop sign in a small town), I've gotten off with a friendly warning. Maybe it'd be different if I wasn't balding and graying. Maybe it's different beyond the Midwest.
But, until the day comes that my convictions cause me to decide to break an unjust law, the police shall be, with few exceptions, my friends.
To the extent that the police exist to enforce the law, and to the extent that I intend to abide by the law, the police are my friends.
In my experience, it seems the overwhelming majority of the cops are on the same side of the law as I am, and we both appreciate that.
I have no doubt of your good experiences with the police. I also have no doubt that the majority of LEOs are the good guys. But, that really isn't the point. The point is this, by its nature the role of the police officer is not 'friendship'. Your experiences so far have been positive, but you shouldn't mistake benevolence, so far, with 'friendship'.
