The problem with this is that an affidavit, which is what a PCA is, should be a statement of absolute fact, to the best of one's knowledge.

LE saying "it could have been blood" isn't a fact. "Could have been yes" is not a fact. Misrepresenting facts in an affidavit is thus problematic, because that is the basis for the charges. Which led to RA being held in a prison for over a year. Nitpicking is kinda important when you are depriving someone of life, liberty and the pursuit of happiness.
