Witnessing a crime is jarring. Get to safety, then sort out what comes next: whether you have to report it, whether you can be made to testify, and how you can be protected. Here's how that works.
In most situations there is no legal duty to physically intervene, and stepping in can put you in danger. If a violent crime is happening, move to a safe spot, then call 911 as soon as you can.
Reporting is encouraged, but most states impose no general legal duty to report crimes you witness. Key exceptions: child abuse (in some states, everyone is a mandatory reporter) and certain professional duties.
Memory fades fast. While it's fresh, note descriptions of the people, clothing, vehicles, the time, the location, the order of events, and anything that was said. These details matter later.
If you're identified as a witness, you may get a subpoena — a court order to testify. A subpoena must be obeyed. You can talk to a lawyer about your testimony and your rights beforehand.
If you're afraid of payback, tell law enforcement right away. For serious cases, options can include witness protection programs, restraining orders, and confidential testimony arrangements.
