Preserve first. Interpret later.
Use this guide when an event is fresh or when you need a map through an older case. It is a sequence, not a verdict: preserve first, define the question, test explanations, and state only what the record supports.
Stay safe. Do not enter restricted or private areas, and do not watch a screen while driving.
Record the exact date, local time, time zone, location, viewing direction, elevation, duration, and weather.
Describe before naming. Count lights or objects; note shape, color, brightness, sound, motion, changes, and visible landmarks.
If it is safe, capture continuous video and wide stills that include the horizon or fixed references. Avoid filters and preserve the original files.
Ask witnesses for separate accounts before group discussion. Keep identities private in review copies and use witness IDs.
