actually there's other thing that not mentioned before in this discussion.
there's two special class investigator that gonna come to see kaneki
ui and washu.
the frist to arrive is ui and he see kaneki as dangerous being especially he's mentality not stable because hairu death
on the other side washu, what he will think about this situation?
washu is someone who think benefit of himself and victory of operation,what if he think kaneki as asset of ccg?
maybe washu will do the same like furata do.
well thats my theory
