Journalist: There is no downside to journalists using anonymous sources. National newspapers require journalists to use multiple sources to corroborate anonymous tips, and corroboration removes any possibility of abuse. Any failure to corroborate sources would risk national security through the publication of misleading information. The strength of the argument depends upon which one of the following? ['Journalists should only use anonymous sources.', 'All journalists work for national newspapers.', 'Journalists should only use anonymous sources under extraordinary circumstances.', 'The government has never infringed on the freedom of press.']
