The voters elected people whose job it was to oversee Boeing, but those elected people failed at their jobs. Why should the voters be held responsible for that? It's not the voters' job to oversee Boeing, that's why they elected people to choose other people to run that agency. The whole purpose of representative democracy is that laypeople aren't qualified, nor do they have the time, to make every decision collectively needed to run a society, so they select qualified people to do that full-time for them. If those people can't do the job properly, or do an especially negligent job of it, they can rightfully be punished or even prosecuted. Your argument is like claiming that a taxi company owner should go to jail when one of his drivers rapes a passenger, even if there was no way the owner could have known the driver had this propensity. It's totally nonsensical. The executives at Boeing are the ones ultimately responsible for the decisions that led to these crashes, because they prioritized profits over safety, and directed their engineers to work towards that end. For that, they should go to jail.
