Interviews are a key element of journalism. But in an investigative report, they require more preparation, better understanding of your story and research on your source, so you can ask questions accordingly. Investigative journalism can be sensitive, controversial and even damaging to reputations. That is why it is important to hone interviewing skills that prepare you for what types of questions to ask, how, and in what order. There are also ethical issues to be considered when interviewing.
