alt Hacker News> Do you really want to apply that to congress, the judiciary, the police. Let's face it anyone in any position of trust, which turns out to be everyone in the end because homeless, unemployed I could be a witness to something.
These kinds of paths to blackmail/extortion are literally what government background checks pressure test when hiring employees. So, yes, we do want to apply those to people in positions of trust.
I'm not clear why you claim this extends to everyone including the homeless and unemployed, that seems wrong to me. You can't blackmail a homeless person into violating national security.
But if you allow them privilege denied the great and the good what message does that send "to the children" ?
Are you really claiming the homeless don't matter?
Even if you can do all these things then you must deny them the ability to testify in court because they could be blackmailed.
If you don't see how this goes I probably can't help you. Read a diversity of sci-fi? Read what life was like in the soviet union?
