Could you post the pic and ask anyone who was involved in an incident with him to make a statement and email it to email@example.com?
There is also a picture of SCD43 with two colleagues. All 3 were operating as a unit throughout the day on Sunday 19th August at Climate Camp. SCD43 was not displaying visible numbers for the duration of the day (but did display them on request). I don’t have the numbers of the other two unfortunately.
