Questions about the Criminal Justice posters
- What is the Criminal Justice section of LearnPosters?
- The system, the theories and the evidence about what works. Criminology, policing, courts and corrections — the frameworks a criminal justice degree tests, and the evidence behind the policies.
- What topics do the Criminal Justice posters cover?
- 100 posters across 7 topics. Criminological theory — Why crime happens, according to whom. Policing — Models, powers, discretion and accountability. Courts & process — From charge to sentence. Corrections — Prisons, probation and reoffending. Forensic science — Evidence types, handling and limits. Victimology — Victims, harm and support.

- Who are the Criminal Justice posters for?
- The criminal justice charts are pitched at undergraduates and professionals — the frameworks and equations a course keeps returning to. Nothing here is tied to a school year, so a curious beginner and someone revising the same material for an exam are looking at the same criminal justice chart.
- Which Criminal Justice poster should I print first?
- What Criminology Studies, Counting Crime and The Dark Figure are the ones people reach for first — they are the references the rest of the criminal justice set assumes you already have on the wall.What Criminology StudiesCounting CrimeThe Dark Figure
- Are the Criminal Justice posters free to print?
- Yes — all 100 of them. Each criminal justice poster is a free vector PDF that needs no account, prints on US Letter or A4, and enlarges to A1 without softening. Home, classroom, library and tutoring use are all covered by the licence.Read the licence
