Then you just make those friends a target. They only need to buy-off or kill 3. It is unlikely the general public would know of them, so it likely wouldn’t be reported on.
Turn it around: require a 3/5 quorum to disarm the public-release deadman switch. Buying off 3 people whose friend you have just murdered isn't going to be trivial.
I wonder if having some sort of public/semi-public organization of trading parts of SSS's could be done.
Right now, as an individual, you'd have pretty small number of trusted N's (from parents definition). With some organization, maybe you could get that number way up, so possibility of destroying the entire scheme could be close to impossible with rounding up large number of the population.
