What about the questions of reliability when it comes to evidence after so long? Most abuse evidence comes from testimony (memories worsen with time), physical (requiring near immediate collection), or forensic (degraded or contaminated over time). If there is digital evidence that stands the test of time it can be very good. But even it can be degraded or partly lost or incomplete.
Cases from a long time ago typically stand on testimony and expert witnesses interpreting behaviors and interviews. It is almost always colored by victim empowerment and the desire for justice and making an example of someone. You might think it makes a good deterrent to prevent abuse. But there is a high risk of false accusations, which even when wrong and proven wrong, completely destroy lives.
We need to concentrate on empowering people to come out immediately. That it is not “okay” for abuse to occur at any age.
