Easy "Detective Chief Inspector" achievement
There two ways to ensure that you have watched every clip. It is impossible to view all clips without one of these methods, because there is a string of clips that consist solely of her saying "Yes" or "No" while hooked up to the lie detector.
Progress as usual until you decide you are finished, then go back in and repeatedly use the "admin_random" command until you have watched every video. Note: You will have to watch videos you have already seen.
Search for "blank", which is the standard tag for every video. All clips will appear in the search in chronological order. After watching a clip, remove the "blank" tag, then continue to the next video. Search again for new videos and repeat the process.
