Donations from Ill-Gotten Gain in Jewish Law and Ethics and in American Law Available to Purchase

These questions are addressed from the point of view of Jewish law and ethics and then from the perspective of American law, with a final section comparing these two treatments of the issues to each other and to what Western theories of ethics would say about this situation.
