I think most people will have realised that as Madeleine was 3. Rowley erred when he stated that, "However she left that apartment, she has been abducted." It was an irresponsible comment for any senior copper to make publicly on national TV after stating that they must keep all options open. It made him look really foolish imo.
Mark Rowley also said that the investigation into the McCann's was done by the Portuguese and that it was done and dusted that they didn't want rumours going around that they were investigating the McCann's. THEN he went on to say the McCann's were parents of a missing child, however Madeleine left the apartment she was abducted. So what do you think he means? Parents of a missing child, seems to say that she is still missing that the McCann's have done nothing. The options could mean that they don't know where she is or whether she is dead or alive, not that the option of the McCann's being involved.
Anyway as to the abductor argument, what is wrong with the 'In my opinion' quote as it is what we have been doing for a long time.
