The following standards are basic for media practitioners and/or TV/RadioPresenter. Identify sources whenever possible. Confidential sources should be used only when it is clearly in the public interest to gather or convey important information or when a person providing information might be harmed. Journalists should keep all commitments to protect a confidential source. Clearly label opinion and commentary. Guard against extended coverage of events or individuals that fails to significantly advance a story, place the event in context, or add to the public knowledge. Refrain from contacting participants in violent situations while the situation is in progress. Use technological tools with skill and thoughtfulness, avoiding techniques that skew facts, distort reality, or sensationalize events. Use surreptitious newsgathering techniques, including hidden cameras or microphones, only if there is no other way to obtain stories of significant public importance and only if the technique is explained to the audience. Disseminate the private transmissions of other news organizations only with permission.
