- Who is the Pattern Evidence Under Review poster for?
- Pattern Evidence Under Review belongs to the Criminal Justice section rather than to a school year, because law & society is not something one grade owns. Anyone learning forensic science can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Pattern Evidence Under Review poster?
- Use it before accepting any pattern-matching conclusion as settled science. A wall chart earns its place by being glanceable from where the work is happening, so Pattern Evidence Under Review belongs on the wall where that law & society work actually happens, within glancing distance, rather than filed away.
