Draft support: "The corrections box made the newspaper more trustworthy." Source notes: editor log: before the policy, 12 corrections were handled through private emails; after the policy, 15 corrections were published in a clearly labeled box with issue dates and article titles. Which revision most effectively turns the general support into verifiable evidence?
