Does chain of custody have anything to do with this? I know in some computer forensics work it is important to be able to prove evidence has not been tampered with. So for example, cracking hashes instead of working with encrypted data can create safe space for non-leo to work without undermining an investigation. For example, a case of illegal doping, the accused Pearson’s samples must be able to be shown to not have been tampered with. It seems being able to prove the source of evidence would be the first step of this process.
