Another change would be to eliminate the section on Level of Certainty. The reason being given is:
This public input is submitted on behalf of the Certainty of Opinion Task Group of the Technical Committee on Fire Investigations responsible for NFPA 921. Substantiation for proposed revision: Revisions in this edition of NFPA 921 to the recommendations for expressing expert opinions are the result of developments in the larger forensic science community that are intended to make expert opinions better serve the interests of justice. To this end the goal is to make expert reports and testimony more accurate and transparent. The second paragraph of 4.5 stating that the final hypothesis must be uniquely consistent with the facts and the principles of science reflects the wording in 4.3.6 "Test the Hypothesis." It does not require perfection.
This is not being submitted by the Certainty of Opinion Task Group of the Technical Committee on Fire Investigations, but by an attorney that sits on that task group.
