Pretrial detention, extending on average 25 days and increasing conviction risk by 20%, not only overburdens judicial systems—especially in countries where it comprises over 40% of prison populations—but also fuels recidivism, mental health issues, and harsher sentencing, prompting reforms that have successfully reduced detention rates and racial disparities while highlighting the urgent need for safer, fairer pretrial practices.

International Perspectives and Comparisons

Internationally, the use of pretrial detention varies widely, ranging from under 10% to over 70% of the prison population, reflecting differences in justice systems

International Perspectives and Comparisons Interpretation

The stark disparity in pretrial detention rates worldwide highlights how justice systems can be as diverse as they are unpredictable, turning innocent until proven guilty into a gamble with high stakes.

The use of electronic monitoring as an alternative to detention has increased by 35% over the past decade
The majority of pretrial detainees are held for offenses that can be effectively addressed through alternative measures, such as community service or treatment programs

Policy Reforms and Alternatives Interpretation

While some jurisdictions have dramatically cut pretrial detention by over half and embraced electronic monitoring to keep cases moving, the continued detention of many for offenses better suited to community-based solutions highlights the urgent need to align policies with evidence-based practices that uphold justice without unnecessary deprivation of liberty.
