The removal of the bike lane seen as a real affront to the cycling community, so a group of “do it yourselfers” went out in the night to try to re-stripe the bike lane. They were apprehended by the Shomrim, the informal police force that works for the Hasidic community, who held these do it yourself bike lane painters until the NYPD arrived. Douglas describes it as a situation where a kind of DIY police force took action against DIY activists — exposing the rifts in the community and showing the limits of informal urbanism.
