Common questions
Why does BEA insist on an assumption-free review before any offender characteristics are inferred?+
Starting without preconceptions about the offender reduces the risk of confirmation bias, where an analyst might otherwise interpret ambiguous evidence to fit an early theory rather than letting the evidence itself define what can be established.
What kind of conclusions does equivocal forensic analysis produce?+
It produces statements about what the physical evidence actually supports, such as the sequence of events or degree of victim resistance, rather than conclusions about offender identity, which come later in the BEA process.
