I was driving, with my 5-year old in the back seat, through a school zone and was subsequently pulled over by an officer who politely pointed out that I had been driving a bit too fast. He could have issued me a citation, but instead encouraged me to observe the posted speed limit in the future. For me, the whole encounter was neither unpleasant or inconveniencing (it lasted 3, maybe 4, minutes). Moreover, the officer's demeanor didn't seem consistent with any authoritarian or revenue-generating motive. Instead, I took away a feeling that this was just a routine episode in a larger public safety mission.
