You are correct. Trying to figure out what happened is impossible because we don't have the proper access to the people, documentation, etc... It's like trying to put a puzzle together with half of the pieces missing. Every "answer" we have as to what happened is just a "theory." Some are better than others, and some would probably be found to be true with a proper investigation, however, spending all of our time trying to figure out what happened is wrong.

It's time for us to stop trying to answer the questions, and instead, it's time for us to start asking them. As a movement. With a loud, clear voice.
