This 84-page report looks at how France uses a vaguely defined ‘terrorism association offense’ to arrest large numbers of people based on minimal evidence. Human Rights Watch documented credible allegations that terrorism suspects are subjected to oppressive questioning in police custody, linked to a policy that delays a suspect’s access to a lawyer. Many suspects go on to spend long periods in pre-trial detention. Human Rights Watch talked to two dozen people caught up in terrorism investigations and trials, and conducted interviews with counterterrorism officials and judicial authorities.
