True-ish Crime: Bloodstain Pattern Analysis

Not the BPA that is commonly advertised as being not in our water bottles (at least I don't think so...), bloodstain pattern analysis is an investigative tool for analyzing crime scenes. Made popular by the TV show, Dexter, BPA attempts to reverse engineer and recreate a crime scene so as to determine important clues. But in real crime scenes, the evidence is very messy, and analysis can become practically impossible. Real experts caution against certainty in using BPA. We will share our findings on the science and misunderstandings of bloodstain pattern analysis.
