The jailbreak though is less plausible than the staying in prison. I am not saying it wouldn't happen in such a game, but living world sandboxes are games where there are often lasting consequences for your actions (I think Arbiter of Worlds does a great job laying out a case for this). If the Gm stepped in and had them broken out, I think that could raise eyebrows in many campaigns. Plausible doesn't mean can happen. It means most likely. And if there are situations where there are lesser possibilities, then many GMs are going to roll. Or they let the players try to engineer their own breakout (but that is played out if it happens). If the whole party is in jail, the campaign might skip to when they are released, or they might start playing new characters. I am not saying breakouts can't happen, I am just saying that in the context of a living world sandbox, a jailbreak that is clearly being done to escape the potential of players being stuck in jail, will come off as artificial and not as guided by plausibilityLet me give a concrete example of what I mean. Let's say the PCs were framed for a crime (or possibly committed one, whichever you prefer). The plausible, but extremely boring, option A would be for them to wait for days or weeks in a jail they don't have the ability to break out of, until a judge finally arrives to hear their case. The slightly less plausible, but still fairly plausible, option B would be for the PCs' allies (who also oppose the tyrannical/oppressive laws of the land) to stage a prison breakout before that happens, both to help the PCs escape, and to have a little leverage over them ("we did break you out of jail...you could at least scratch our backs in return" kind of thing). A prison break specifically to help the PCs is simply, flatly, less plausible than the prison working as it has always worked. But it's also a hell of a lot more fun--and, importantly, still quite plausible, even if it is ever-so-slightly less plausible than the alternative.
This wasn't sandbox game, but in my mafia RPG, I gave prisons different ratings of security to deal with players trying to escape. Even outside sandbox play, it isn't something I would just make happen
