Mounted police geared up like this project strength and low-key swagger. In our photograph I think the isolating of certain details adds to this impression, beginning with the powerful hindquarters and flanks of the horses, and continuing among the luxurious folds of the officers’ leather jackets. Three of anything brings to mind a triangle or pyramid, strong interlocking three-pointed structures. Above we have three cops, three sets of blue trousers, three sets of fine leather goods. For me their three blue helmets make the strongest impression, because they each incorporate a reflected image of the city these guys protect.
