Toronto's drug policy paradox: Harm reduction sites and drug police occurrences in Toronto neighborhoods (1992–2020)

Criminology, EarlyView.
Abstract Discourse around drug policy presents a stark contrast between policing and harm reduction models, sparking debates on the state's regulatory versus protective role. Canada is an ideal case to study drug policy models due to its global recognition as a leader in harm reduction alongside continued reliance on policing of drugs.

Focused deterrence can reduce crime: A systematic review of randomized controlled trials and quasi‐experiments

Criminology &Public Policy, EarlyView.
Abstract Research summary Crime and violence continue to be problems that plague urban areas across the United States and the globe. One key approach for responding to these problems is “focused deterrence” which includes programs that prevent criminal behavior by blending criminal justice, social service, and community‐based action.

Sanctions, National Security, and Free Speech

Global Policy, EarlyView.
ABSTRACT A fundamental, but largely overlooked, aspect of the New Washington Consensus is the use of national security arguments to restrict speech and punish disfavored speakers. Although the United States has a longer history of using sanctions to restrict speech in the terrorism context, it has recently applied sanctions to restrict political speech,
