Investigative journalism

nvestigative journalism is a form of journalism in which reporters deeply investigate a single topic of interest, often involving crime, political corruption, or corporate wrongdoing. An investigative journalist may spend months or years researching and preparing a report. Most investigative journalism is done by newspapers, wire services and freelance journalists. Practitioners sometimes use the terms "watchdog journalism" or "accountability reporting."
As part of an investigation, journalists make use of:
Analysis of documents, such as lawsuits and other legal documents, tax records, government reports, regulatory reports and corporate financial filings.
Investigation of technical issues, including scrutiny of equipment and its performance
Research into social and legal issues
Subscription research sources such as LexisNexis
Numerous interviews with on-the-record sources as well as, in some instances, interviews with anonymous sources (for example whistleblowers)
Federal or state Freedom of Information Acts to get documents and data from government agencies.
