There is a good reason why research ethics reviewers ask about where a consent strategy will be conducted, who will be administering the consent process and whether any implicit coercion will be used.  Hopefully, no one would ever use organised crime thugs to administer their consent strategy, in an isolated room and at least the impression that violence would follow if potential participants don’t ‘sign’.  That notwithstanding, part of you has to chuckle at Don Mayne’s conceit here.
