>Would shutting up have resulted in less jail time?
Talking will never, absolutely never, result in anything but more jail time. There is absolutely zero benefit for you to answer police questions past basic things such as identifying yourself/things like showing license/registration at a traffic stop. At no point would talking ever make your case better.
Also, it should be seen as a torture situation: they are professionals that will throw the full arsenal at you, including delaying your requests as long as they can get away with (I assume there can just lie about getting you a lawyer and have your requests memory holed. BTW do you even have rights to one depending on what form they took to keep you ?). They can put physical and mental pressure on you for days and days, and your only path is to shut up, if you’re not willing to give them what they want. And at no point you can afford to break down.
Overall, that’s a stacked game I’m not sure you can really win depending on how dirty they want to play it, except if you get external help that they couldn’t shut down.
