From the article, it sounds like they record every single innocuous interaction. The city portion of Charleston is fairly small, confined to a small peninsula. Given the small size and not-so-large population, there are actually quite a few well-known bums in the town that one would just run into every day or so walking to and from work, usually in one of the major areas of the city. So imagine if you've got cops working the streets, it's totally conceivable that one or more officers run into one of those guys several times a day.
