单选题
Reporting on a civil war, a journalist encountered evidence that refugees were starving because the government would not permit food shipments to a rebel-held area. Government censors deleted all mention of the government's role in the starvation from the journalist's report, which had not implicated either nature or the rebels in the starvation. The journalist concluded that it was ethically permissible to file the censored report, because the journalist's news agency would precede it with the notice "Cleared by government censors." Which one of the following ethical criteria, if valid, would serve to support the journalist's conclusion while placing the least constraint on the flow of reported information?
