How about prohibiting them from holding executive positions in the future?
But if we really can't attribute blame to specific individuals, your proposal is effectively collective punishment where individuals that are genuinely innocent are punished because of wrongdoings of other members of the group. From a justice perspective, we're in murky moral waters. An analogy would be to punish everyone in a shared household if we know that one member of that household committed a crime but we can't determine which one specifically (and let's assume that the innocent members of the household don't know and aren't hiding information). This would be a state of affairs that everyone would rightly protest. So we need to think carefully as to whether we want to enact your proposal.
The ultimate point being: you can still let them make decisions about their own lives if you want, but that doesn't imply you have to let them make decisions that affect other people's lives.

They didn't even touch the Sheriff.
> Sheriff Laurie Smith, who has the authority to issue CCW permits, has not been charged with a crime.
Either i. the sheriff knew about/was in on this scheme and must be put in prison or ii. the sheriff didn't know about how her number two was soliciting bribes using her authority to grant/deny licenses and must resign because that is just gross negligence.
Which one is it?
In principal, it strikes me as a good idea - it promotes collective good behaviour, and responsibility for ones peers.
