Over the last four decades, the American criminal justice system has undergone a dramatic expansion, which has drawn increasing attention from sociolegal scholars (i.e., Kohler-Hausmann 2013; Natapoff 2012). Analyses customarily proceed from a nowceremonial retelling of incarceration statistics: 2.2 million people currently sit in jails and prisons while roughly 5 million people are under some form of correctional supervision (Glaze and Kaeble 2014). Yet while these numbers are staggering, they "both underestimate the reach of the criminal justice system and, in some sense, misrepresent the modal criminal justice encounter" (Kohler-Hausmann 2013: 352). Indeed, incarceration and community supervision are but the tip of a larger iceberg. Below the surface, and often eluding official record keeping, are millions of street-level police stops, infraction citations, and low-level arrests. The best estimates suggest that roughly 40 million people have face-to-face contact with police per year (Eith and Durose 2011). Excluding routine traffic stops, 5.5 million people are involuntarily detained by police every year, the majority of whom are released without charge (Brayne 2014). Disproportionately directed toward poor communities of color, recent criminal justice expansion subjects the country's most disadvantaged residents to a consequential form of street-level criminalization in which mundane public behaviors become subject to intense police suspicion, interrogation, and intervention.This article develops a systematic framework for more adequately analyzing the lived consequences of street-level criminalization. Specifically, it demonstrates that the constant threat of police contact operates as a powerful "cultural agent" that significantly transforms the cultural contexts and social relations of poor communities of color (Garland 1990). This study extends several areas of sociolegal research by bridging scholarship on the collateral consequences of criminal justice contact with cultural analysis. Researchers are devoting increasing attention to the diffuse and deleterious effects of criminalization on the social health and stability of marginalized communities. Cultural analysis provides key conceptual tools for understanding how and why the criminal justice system generates patterned systems of understanding and action among criminalized populations even when criminal justice actors are not actively present. The following pages illustrate that in communities where the threat of unwanted police contact and enforcement looms constant, residents develop and refine a particular cultural frame-what I term "cop wisdom." Cop wisdom allows these individuals to render seemingly-random police activity more legible, predictable, and manipulable. Armed with this interpretive schema, "copwise" residents engage in creative and circumspect tactics for evading, deflecting, and subverting criminal justice interventions.In the tradition of legal consciousness scholarship, this article thus "de-centers" the law by shifting emphasis from formal legal institutions to the informal processes by which the law "invokes commonplace schemas of everyday life" (DeLand 2013; Ewick and Silbey 1998: 17; Saguy and Stuart 2008). In doing so, the article reveals a pervasive, though unexamined mechanism by which heightened law enforcement (re)produces inequality: While cop wisdom may enable residents to reduce the likelihood of police contact, they often deploy this frame in a manner that constricts vital social interactions, contributes to animosity in public space, and undermines individual and community well-being.Collateral Consequences of CriminalizationCollateral consequences, or "invisible punishments," refer to the negative effects of criminal justice involvement that typically manifest outside of the traditional sentencing framework (Hagan and Dinovitzer 1999; Travis 2002). Rather than being imposed by the decision of a sentencing court, these effects occur by default through associated social processes. …
