Bite mark evidence is not backed by scientific research, but has been used to put many people in prison, potentially wrongly. Here is an article that discusses this issue https://californiainnocenceproject.org/issues-we-face/bite-mark-evidence/. John Oliver of Last Week Tonight also featured the pitfalls of bite mark evidence being used at https://www.youtube.com/watch?v=ScmJvmzDcG0.

I want to propose a law that states:

Bite mark evidence may not be used in any trial for any reason until the following conditions are met:

Condition A: 3 peer reviewed scientific studies confirm the validity of bite mark evidence as reliable evidence in court for a criminal conviction

Condition B: The use of bite mark evidence is approved by the federal Department of Justice of the United States of America after Condition A has been met
