Tiger is only ten, and the legal system holds that people of age ten are assumed to be children unless they explicitly petition otherwise, and also that such children are not fully responsible for their actions, and most kinds of non-catastrophic "mistake" ought not be held against any adults they might later grow up to be.
No you couldn't. They could all set up hidden journals that would be found if they died, that reveal everyone else in the conspiracy, and if they don't want to get betrayed they'd obviously choose to do that, so you'd expect killing your allies gets your whole plan leaked in retaliation.
But the government could just guarantee that'd never happen by telling everyone in advance that they could do that, which they'd want to do anyway since it disadvantages criminals.
No, it advantages criminals to know that, since then they know they can't easily kill each other and can coordinate better, so the government wouldn’t want to tell them about it.
Ha! If the government doesn't want it done, then I'll do it. Hey kids! You can get better coordination in all your criminal conspiracies by leaving dead-man's switches set to leak all your co-conspirators' names in the event that any of them betray you!
Then you definitely shouldn't be allowed to make plans that involve killing your co-conspirators to stop them testifying. It wouldn't ever work.
If it wouldn't ever work, why should we need to stop bad guys doing it? They can just do the plan and then it fails and then they get caught.
No because it does work but only if they're not really getting killed. They're only pretend-dying, so they can just negotiate beforehand to split up the loot afterwards.
So something like, if you betray one of your allies by pretending to kill them, you're not later allowed to give them any of the loot? And because they can't get the loot later it'll never be in their interests, so they'll always choose to set up a dead-man's switch to betray you back?
What happens if they just agree to that, and then secretly give them a share of the loot later anyway? They are criminals, after all.
The Harms Commission knows who they are and is watching, even if the guard haven't solved it yet.
They can dob them in if they do something against the Harms Commission rules, even if they aren’t allowed to dob them in about anything else.
We're allowed to get people arrested for stuff now? But only for things where they break their agreements with us? This is getting pretty confusing, I think I need a diagram.
Mwahahaha! Then I've got no choice but to give you all homework!
And as a clever supervillain, I've of course foreseen this very eventuality and prepared worksheets in advance!
