1) Ethical limits on law enforcement. Should all good laws be enforced? Should all important criminal laws be enforced with prison?
2) Economic civil disobedience and the ethics of obeying the law. When, if ever, is it OK to treat fines as a cost of doing business?
3) Transactional justice. Consent is not always enough to make an economic transaction ethical. What else is needed?
@Azure By "prison," I mean involuntary confinement that
physically separates people from the rest of society.
It's an interesting and difficult question whether other restrictions on movement, such as house arrest and the use of ankle monitors, raise the same ethical concerns as prison.
