Surprise Vs. Probability As A Metric For Proof, Edward K. Cheng, Matthew Ginther Jan 2018

Surprise Vs. Probability As A Metric For Proof, Edward K. Cheng, Matthew Ginther

Vanderbilt Law School Faculty Publications

In this Symposium issue celebrating his career, Professor Michael Risinger in Leveraging Surprise proposes using "the fundamental emotion of surprise" as a way of measuring belief for purposes of legal proof.

It concludes that body camera footage is distinct from evidence traditionally admitted through those frameworks because body camera footage is akin to an officer's assertive statement--the officer has discretion to activate and aim the body camera. Courts should therefore exclude the footage …
