They both have to deal with the public. When drinking in bars, people tend to go to extremes of their personalities. If their a jerk, it increases. Cops often have more to attend to around full moons, generally with alcohol and drugs involved. Bartenders see more fights and just weird happenings around the full moon. I've been told by a bartender that she can always tell when there is a full moon, about 3 days of it...just the strangest stuff happens.
When you're old enough to get in a bar, ask some bartenders. See what their opinions are.
Or...maybe it's just folk lore. We believe it, so when weird things happen, we chalk it up to the full moon. It's like buying a car, and once you own that car, that color, you notice every car that drives down the road that is the same make and same color. Before buying it, you never even knew that car existed.
Such a society would be dominated by an elite, unrestrained by traditional values. Soon it will be possible to assert almost continuous surveillance over every citizen... - Zbigniew Brezhinsky
