Its a fair assessment if it cannot be found in recording in this day and age it probbly is uncommon to happen. I will make exemptions for poor countries, but even then. smartphones are the norm now, and phones with cameras are as well. Alongside CCTV being pretty common and not that expensive to get. Hell even if you cannot find a police report or witness testiomony of a event. If you cannot find any evidence of a event would you belive it happened because somone you dont know told you it did? Now that would depend on you soley.
