I swear if I am ever a whistleblower I am going to hire someone for minimum wage to hang out in my hotel room while I sleep and they can play on their phone, eat burritos, and play video games until the trial is fully over. And also make sure they have the ability to livestream the moment something weird happens.
Also I don't know put a thousand or so videos on YouTube with email links to everyone I have ever known with me saying all the damaging stuff and that I am not suicidal.
$60 or so dollars a day is worth it to me to not get silenced like a fucking Russian critic.
Cameras everywhere, all the time, backed up to the cloud in multiple locations. A copy on a private server would be ideal. It's not foolproof but it's better than nothing.
You can still be silenced like a few US presidents. Or even blown up with explosives. Even the government pulled that one on those anarchists in Philadelphia. Because wiping out your entire neighborhood to get rid of you could very well be on the table.
