Penultimate Amazing
Firstly, as I and others have already pointed out in this thread: had she felt she had the right to obtain third-party verification (eg by contacting 999), the odds are that he wouldn't have gone through with his horrific plans - for reasons which ought to be obvious.
And secondly, the post of yours to which I'd been originally responding (and which therefore kicked off this exchange) framed things in terms of Everard "being stopped by a menacing figure". I responded by pointing out - entirely correctly and obviously - that this man almost certainly wouldn't have seemed "menacing" to her at that particular point. He would have seemed to her to be a police officer who was performing a duty. A duty which yes, she might have found frightening in and of itself (not many people enjoy being arrested etc), and one which she might have felt he was rather too zealous in performing. But nothing more than that. She most certainly cannot have thought, as she was sat in his car waiting to be driven away, that any physical harm was going to come to her at his hands. (Which only serves to make the whole thing so much more tragic and heartbreaking still)
OK, so the average man would not be at all concerned. A young attractive woman who is approached almost every day just for walking down the street by pervs (who look like ordinary men) would almost certainly have thought 'Oh no, not again' as this imposing creature, bulked up by his stab vest and police vest, together with bulky pocketed trousers suddenly appears in front of her on a dark evening from an unmarked car parked probably in a no-parking area. Of course, seeing his police ID card would be initially reassuring, but the moment he twisted her arm behind her back and forcibly handcuffed her and manoeuvred her into the car, no way was she comfortable. I think her only chance would have been to kick the creep hard in the goolies but of course 'nice girls' aren't even taught to think of that.
Your claim, "She most certainly cannot have thought, as she was sat in his car waiting to be driven away, that any physical harm was going to come to her at his hands", of course, might be true, but I am afraid I am highly sceptical about this. I think it would have been more of a hope.
