Trial by media the only option Scott Morrison and Christian Porter left open

I find this exasperatingly stupid.

The only reason we now have people like Andrew Bolt and even his ideological enemy Phillip Adams attacking or questioning the credibility of a rape claim made by a deceased women (Adams tweeted concern about Crikey reporting that it may be a case influenced by recovered memory therapy - or theory?) is because Morrison and Porter tried to tough it out by pretending that a Police non investigation is the same as an actual investigation.   

So now we have the unedifying spectacle of Bolt publishing an example of what was in the material the women's friends sent to politicians, and attacking Labor for saying it was a "credible" claim, and tonight we will have Four Corners presumably with a few people the deceased knew saying that she seemed credible in her recall to them.

It could all have been avoided by Porter stepping down while a discrete, independent inquiry was held.  Seems to me it could have been finalised within 4 to 6 months, tops;  and the media would have stopped talking about it.

PS:   if there is stuff in the dossier that makes it look like an independent investigation would find insufficient grounds for acting on the complaint in any manner - how stupid does Morrison (and Porter) look for taking the apparent tactical decision ("can't blame me for not acting if I didn't read the material") of saying they had not read the details before deciding no investigation is warranted?
