If you're meaning 'a convicted criminal guilty of a heinous crime' when you say "corrupt person" then why do we even allow them the ability to continue financially such that they can buy an appearance of legitimacy. Release them from prison with access to basic necessities (a half way house) and confiscate the rest - then the demos can direct the money to research without tainting it?
