Another quote from the same article: "The Judge reminded the court that he applied the lowest standard of proof in the U.S. Court system. “There is a reasonable belief that the defendant may have committed the crimes charged. I must draw all reasonable inferences in favor of the prosecution. The evidence to support a conviction of the crime is not necessary at this stage of the hearings.” He reminded the court that evidence that wouldn’t normally be allowed, may be allowed at a preliminary hearing such as the one that was concluding that day."
We often forget this sentence as well. And I am not talking about only the DNA evidence.
The Judge didn't make his decision based on inadmissible evidence - the Judge knows how to approach such evidence. This was no special benefit to the prosecution.
My general point is you can't take statements from bail hearings or prelims and apply them to the trial itself.
The key evidential question about DNA cannot be resolved in a prelim or bail context
