GNR officers' statements.
As Jassi said, one patrol car carrying 2 GNR officers & one supervisor at HQ were the only ones on duty that night. We can only speculate who would have dealt with any major disturbances in Lagos.
I think it was the perfect storm.
I've lost the cite given by you some time ago, of Madeleine's disappearance coinciding with a huge police celebration the previous day complete with police dogs et al in conjunction with what police who were on duty that night being diverted to check out an alarm going off elsewhere.
Maybe the diversion if there was one, was to cover for something else entirely and unrelated to Madeleine's disappearance, on the other hand, did anyone check out the coincidence?
When Joana Cipriano disappeared a fair was being held in her home village close to Luz.
Snip Ophelia Zeferino helped, incidentally, the family trying to find the child, the night she disappeared, walking the neighbourhood, and even looking to find her among the people who were at the fair that was in the village.
