That is one detail I am puzzled by. How could he not have had a deadman's switch? It should be the only way to prevent a rather large number of people who'd want to off him, from doing so. Yet, assuming he had such a deadman's switch, it would seem it was successfully neutralized. How did they find it? Or, if there were multiple, how did they find them all, and then be confident they really got them all? It's the old problem of not knowing what you don't know.If only Epstein set up a deadman’s switch.
If I were engaged in activities that would require a deadman's switch, it seems pretty easy. You have your data out there and online, in many many places in many countries, e.g. videos of Clinton boinking underage girls, etc. It can already literally be out on the Internet for the public to at least see there's encrypted data out there, but they don't know from who or why. All you need is the decryption key to get out. You can manage that the old fashioned way, by having a couple of trusted friends ready to send it out should you end up dead. That can be risky of course, since you have to be absolutely sure they are trusted and also don't get compromised. It's probably better to put some software out there online in a bunch of places that requires you log in once a week to tell it you're alive. If the software gets no response within a week, it sends out the key. Such a system would of course require redundancy, and use some kind of secure mechanism for getting to it from your devices without them being able to know where you are going, maybe a onion site on TOR or something like that.
Yet, nothing happened. He's either really stupid and bad at this, or I'm missing some very important detail.
