To this date NOBODY knows what the fuck is even in that stupid letter…do you? Then sauce it otherwise STFU!
Since day 1. Even prior, if we want to speculate further.
This is my point, we still have to account for evidence of some kind. There are many theories that could be applied to the "letter" at the funeral. We can't reserve our thought process to the status quo narrative either though. We have to consider all angles.
