Criminal Investigation Path

One case, eight ways of seeing it: scale sketches, stain angles and skid-mark speeds, how fingerprints, DNA and trace evidence are really processed, why honest witnesses can be wrong and how tunnel vision starts, phones, hashes and facial recognition, from Locard’s lab to the wrongful convictions of David Milgaard and Guy Paul Morin, notes, interviews and Charter rights, the CSI effect vs reality, and running a careful mock case with a chain of custody. Made-up cases only, never graphic. Self-directed modules for curious learners, 13 and up, adults included. Type, tap and draw right on the pages.

Lens 2, The Science of Criminal Investigation, is open to everyone. The other seven lenses are for members: log in to open them. Each module works on its own, so start with whichever grabs you, and save Lens 8 (Execution) for last: it leads into the capstone in the printed book.
