‘Peter H., the Monster of Brabant’. In the Netherlands, TBS is a special measure judges can impose on people who have committed a serious crime and suffer from a personality disorder or a serious mental health problem or both. It is a unique combination of prison and psychiatric care. TBS policy is under constant pressure, not only in light of cases where patients have escaped during leave from treatment facilities, but also because the recommendations regarding the continuation or termination of treatment tend to vary greatly. The ZEMBLA episode ‘Peter H., the Monster of Brabant’ takes a closer look.
