Other mistake: When Solomon Lane is being extracted out of the sunken truck there are two divers breaking in. However just a moment later only Benji surfaces with the prisoner while Luther is on the lookout on the rib. (00:55:11 - 00:55:36)
Other mistake: When Benji takes off the Wolf Blitzer mask, he continues to talk with the anchorman's voice until he takes off the voice altering tape too, but when Walker realises that he is not talking to Solomon Lane and proceeds to rip off the mask, Benji talks with his own voice without taking off the tape.
Answer: Nils Debruuk could be Norwegian by nationality, rather than by race if his parents, Grandparents, etc. immigrated to Norway. He may also be part Norwegian on his maternal side if his mother had a child by someone from another country. It is also possible his mother was full-blooded Norwegian and his father was half and had a non-Norwegian father. There's a number of possibilities. I did an Internet search on the name. In that form, I didn't find anything as a surname. There is De Bruuk, which is an area in the Netherlands.
