> OTOH if these techniques and vulnerabilities were made public it would benefit cybercriminals as they could defend themselves better. That same logic applies to any sort of forensic technique, but it's a basic precept of the US justice system that an accused can see and respond to the evidence against them, including questioning the scientific validity of how that evidence was gathered. Just because a technique is "cyber" doesn't mean an accused magically doesn't have a right to know the chain of custody, techniques used etc.
