I was on a project this week where I had lots of time to observe a street alongside one of San Francisco's 'square' parks.
From about 2:30 to 5:00, a patrol car was circling the park. As in it drove up the street I was on, turned right, and 4-6 minutes later, it was back again. At one point I took a break to watch from another location--indeed, it just drove all the way around the park. For two and a half hours. Maybe more. It also showed up again some time after sunset, but by that point I wasn't observing the street regularly enough to see if that was just once.
What was going on? As far as I can tell the two officers inside were not watching for anything.
