What to do if…
you are asked to identify someone in a photo lineup or video and you are not confident

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Do not guess. Say clearly, “I can’t make an identification” or “I’m not confident enough to identify anyone,” and ask for that uncertainty to be recorded.

Do not do these things

  • Don’t pick the closest person because you feel you should help.
  • Don’t let anyone talk you into sounding more certain than you are.
  • Don’t discuss the lineup, photo set, or video with another witness.
  • Don’t search online for photos or videos to check, because it can blur what you remember from the incident and what you saw later.
  • Don’t sign anything that says you identified someone if you only meant “looks similar” or “I’m not sure.”
  • Don’t change your original description to fit the images you have just been shown.

What to do now

  1. Use one clear sentence. Say, “I’m not confident enough to identify anyone,” or, “I can’t identify anyone.” If someone looks similar but you are unsure, say, “Number __ looks similar, but I cannot identify them.”
  2. Ask for your uncertainty to be recorded. Say, “Please record that I am not confident enough to identify anyone.” If your words are summarised as an identification, correct it straight away.
  3. Ask what procedure this is. Say, “Is this video identification, an identification parade, group identification, confrontation, or photographs? Which local code or procedure applies?” You do not need to know the legal label before saying you are unsure.
  4. Take the time you need to avoid guessing. Say, “I need a moment. I don’t want to guess.” Look carefully only at what you are officially shown as part of the procedure.
  5. If you feel pushed, repeat your position. Say, “I’m not willing to guess. Please note that I am not making an identification.” Ask to speak to the person running the procedure or a senior officer.
  6. Keep your first memory separate. If you gave a description earlier, ask whether that first description has already been recorded. Do not update it just to match a person in the lineup, photo set, or video.
  7. If police say you are a suspect, ask for legal advice. Say, “I want legal advice before I agree, refuse, sign anything, or answer further questions about this identification procedure.” If you are under 18 or need support because of vulnerability, ask for the support person or appropriate adult required locally.
  8. Check anything you are asked to sign. Read it slowly. Ask for wording to be changed if it turns uncertainty into certainty, such as “identified” when you actually said “looks similar but I am not confident.”

What can wait

  • You do not need to decide now whether to complain about how the procedure was run.
  • You do not need to explain memory science or prove why you are uncertain.
  • You do not need to chase case updates today.
  • You do not need to decide what might happen later in court.

Important reassurance

It is acceptable to say you cannot identify anyone. A careful, honest answer is safer than a guess, even when you want to help.

Scope note

These are first steps for the moment you are asked to identify someone. Later decisions about statements, court, complaints, or suspect rights may need specialist legal advice.

Important note

This is general information, not legal advice or professional advice. Identification procedure rules are not identical across all parts of the UK, so ask which local procedure applies and get legal advice before continuing if you are unsure, feel coerced, or are being treated as a suspect.
