Recovering data is not the same as producing evidence. For findings to be relied upon and to withstand challenge, they must be obtained and handled to recognised standards, by competent people using sound, repeatable methods. Standards are what separate credible evidence from mere data.
What the standards require
- Methods that are sound, documented and repeatable
- Integrity preserved and demonstrable throughout
- Competent, qualified practitioners
- Clear, honest reporting of findings and their limits
Repeatability and honesty
Sound forensics produces results another competent examiner could reproduce, and reports them honestly, including uncertainty and limitations. Overstating what evidence shows is as damaging as mishandling it; credibility rests on rigour and candour alike.
Why it matters to the outcome
Evidence that falls short of these standards can be challenged and dismissed, however significant it seemed. Working to recognised standards from the outset is what ensures the effort of an investigation produces something that actually stands up.
