The bulk of the protesters may well have been standing back (although I did not see that happen), but not all. Perhaps they did not wish to recognise her legitimate complaint and it is they who are at fault. Not very sympathetic behaviour given what they were there for.

Given the nature of the protest and the very apparent level of anger the Police could not have let her through as it is very easy to see that this would have precipitated a rush of 'protestors'.

It looked like a publicity stunt and probably was. If it wasn't, she should have realised that it was not an appropriate way to register her complaint at that time. The phone would have been a better method, as an example. There were other avenues open. Choosing the most public, with easily foreseeable results, does not engender much sympathy.

how dare you say what the most appropriate way is for a woman to complain about sexual abuse.

This shows how far away the bulk of the protesters were: indymedia.org.nz/usermedia/image/10/jfrs2.jpg
There was NO possibility of a rush of protesters.

You may be right. But, I can't see the woman in this photo. I have no idea if it was taken while she was trying to gain entrance or not, so at this stage I am still not convinced.
