As I previously indicated, the concepts of “Mistake of fact” and “Mistake of law” represent a very specific thing on their own and that specific thing only. They do not refer to a mistake made by any other party except for the accused. Mistake of fact does not refer to any random party’s mistake as to facts and neither does Mistake of law refer to any random party’s mistake as to law. Generally Mistake of fact is a defense, whereas Mistake of law is not. A cursory google search will confirm this for you. It isn’t backwards.
I get that you’re saying police officers are allowed to be mistaken as to facts and acts predicated upon an honest mistake as to the facts of a situation will be deemed valid whereas acts of police officers predicated upon a mistaken understanding of law are not valid. In that sense your post was accurate.
Broadly categorizing and labeling what you were referring to as Mistake of fact and Mistake of law is improper. Throwing around inapplicable legal concepts is not only wrong, it can mislead, especially those unfamiliar.
