We enter into this thread with one important bit of knowledge:
We don't truly know what we will do in any situation until it acutally happens. But it's fun to speculate.

This is a sort of "What if..." thread. Pose your own question and/or answer other people's questions.

When posing a question, offer a few positives and negatives, not merely the question.

I'll start.

Whether by intent or accident, you've discovered a way to view actual events of the past. You can't interfere in the past, but you can view any moment in time, in the past, that you wish.

Question:
Do you share this discovery with anyone else, whether the whole world or only select individuals, keep the discovery to yourself, or destroy the discovery?

Positives:
(1) Finally, history can be seen as it occured, not merely as it was recorded.
(2) Ability to use the discovery in the justice system, allowing actual events to be viewed and not limited to "hoping we got the right person", among other improvements to the justice system.
(3) You can find lost items by seeing where something was lost when you didn't realize it.

Negatives:
(1) Someone's going to be severely disappointed when major history events didn't occur how they believed or how the events were written. Religion and/or science could be in major turmoil after some results.
(2) Important figures could be just as easily seen at their worst, or even be found out to not be as "good" as previously believed.
(3) Misuse by unscrupulous attornies, among others, to misinform judges and juries about events (only events can be seen; thoughts cannot be heard so speculations can still be made).
