False positives are inherent to the justice system. While unfortunate, they do not cross any lines or send us down any slippery slopes. They are priced in. Thus, "what about google" is a mere "what-about-ism". People are ocassionally falsely accused, charged, and even convicted of crimes. That is not what is under discussion here.
