Again, you're concerned with the court's stamp of approval. All a court does is give the gov't a process for determining punishment and assigning blame. The crime happened regardless. It's independent of the judicial system. Did the act described by the legislature take place? Getting a conviction doesn't change what happened in the past.
Let me put it another way, a court convicts a man for a crime he didn't commit. By your logic, he committed the crime because the courts determined it to be so. The courts retroactively changed the past and had him commit the crime. This is the way people who do not believe in an objective reality talk. It's essentially a form of insanity. That objective reality exists, with or without your consent. Courts don't change the past.
