I agree with you. I think we're simply going around in circles because English is weird.
People who have not yet been found guilty are presumed to be innocent. You are absolutely correct. However, the statement I disagreed with was different. It was "If someone is found "not guilty" of murder then legally that person has not committed murder." Legally, that person is presumed innocent, like everyone else, but being found not guilty grants no special "definitely didn't commit murder" status.
