Not every incident is finished the moment it is first logged. A log entry adds a timestamped update to an existing report as the situation develops, rather than editing the original text and losing the sequence of events. Use a log entry for anything that happens afterwards, and edit the original report only for a correction to what was already recorded.
Requesting a statement
If a witness needs to provide their own account, send a statement request from the incident page. The recipient gets an email with a link to submit their statement directly — no E-DOB account or login required on their end.
