I have looked carefully at that video and was going to post with regards to Borce, but deleted as I know I am fighting the tide in finding the guy credible. When the question is put to Borce, Patricia intervenes immediately, and very quickly the woman in the black jacket with furry hood is the one to end the interview. As confronted, Borce begins to move side to side in some distress, but it is only once the woman wearing black says "ok let's end this guys" (or similar) does he turn and walk away as she gestures to them to move away. Then the woman stands between them and the reporters as Patricia speaks again. I am assuming she is a media liaison for the police and the understanding was that Borce and Sarah were not going to talk.
I can imagine him clarifying a question shot at him about the CCTV when the answer is straightforward and the alternate view has been skewed against him in the press but when pressed about doing another "appearance/appeal" he sites the police as the reason he isn't. I can also fathom the police having a blanket statement that they don't discourage people from speaking to the media that the reporter trots out to contrast to Borce's statement - but given the last media appeal looks to be organised with police and ended by police, and they stayed silent through the allegations ... seems neutral to me as to his involvement.
I don't see this one as being half as clear as GBC, or the other fools who murder their wives and come up with a silly story ... time will tell, I've been wrong before.
