JK, nice to see you had happy hols. I'm on the last day of mine but have spent it in dear old blighty catching up on things that just seem to slip by...
As for being too optimistic on the media...even with reflection and thought on this article I don't think I would shift from a basically cynical position on whatever they do.
While the position of the article is that the legal process in cases of this nature has been corrupted by a bunch of self-interest groups - including 'victims - and that truth is the casualty along with innocent people who are forever tainted, the article is of little real substance.
It is a think-piece, nothing more than an exercise in polemic perhaps, if you look at the comments it has generated - but that shows what you are dealing with out in reader land. The article criticises aplenty but does not create any depth by seeking out responses from anyone to these important issues of charge-bundling, anonymity of the accused, compensation tariffs etc. Don't forget today the NOTW launched 'Code Madeleine', it's latest exercise in self-aggrandisement, sorry it's latest crusade for child safety. Whatever it is it's action, not talk or an article. Wait till you see these articles in the 'intelligent' media appearing regularly - particularly in the right wing media - pressuring the relevant elements on their behaviour and the flaws in the system with the potential to effect a change and you might have something.
But the Cops want the publicity to 'find' victims and the CPS are basically obliged to pursue any allegations of sex crime. That needs to be fixed as does charge-bundling, anonymity for the accused etc.
Maybe if there hadn't been so many recent high profile celebrities falling victim to this new industry there wouldn't be any such discussion either and that's what is needed - more high profile cases to further the discussion! There have been dozens of deaths (murders) over the last few years of people accused of sex crimes - before any trial - but while I saw papers like the Guardian and Independent discussing these same issues, the argument, particularly on anonymity, isn't any further forward.
So if things do change JK you can take credit for that because it will be the high profile cases with 'celebrities' that create the debate and will effect change where the murders of others did not.
Throwing out a few other ideas: you might also think that entities such as the House of Murdoch are a bit cheesed off that these cases are now a whole cottage industry where they have to wield their chequebook through a minefield of Police informants, other agencies' informants, witnesses, victims 'Agents' etc. rather than just locking in the exclusive before the Mirror got there as it used to be...So the article may be a critique of a dark little industry they are no longer masters of.
You might also say it is simply a new angle for the more intelligent media having exhausted the 'lock 'em up and throw away the key' approach. After all, they are the 'intelligent' media so they are supposed to challenge things.
You might also say it's just a clever way of fanning the flames by looking intelligent but again, going back to the response it's generated in the comments section, it's just fanned the flames of outrage of Mr. Disgusted of Middle England rather than seeding an idea for the future.
You might also say going out to left field that this new perspective falls out of the War on Terror as the corrupting of the judicial process and civil liberties is proceeding at a terrible pace as a result of it. The arguments against surveillance Britain and what to do with offenders don't really carry much weight when it's a child safety issue but all this 'Terrorist' activity has shown up high profile conflicts and weaknesses in all the same parties - the media, judiciary, politicians and problems of the same sort experienced in sex crime cases - trial by media, hostile approach by CPS/Police - so maybe a re-think on one issue is now appreciating the wider implications.
This answer has turned out to be longer than I expected but anyway...I think there is a hint of change but it's not being driven by the media. We are seeing more and more cases of this nature being seen to be deeply, deeply flawed. If it was any other topic then we'd have seen more scrutiny before now so I think that IF any change comes it will be a media response to the obvious flaws in the system shown through persistent legal failures than any proactive assessment of the situation. Let us not forget though that in rape cases they are now trying to change the rules to make the accused more convictable so fixing the system will not always bring what you'd want.
As for guilt - well the Catholics do it like noone else

I think the probably we are dealing with here though is a shift in moral perspectives. It seems to be traditional for one generation to look down on those coming through with a disdainful 'it wasn't like that in my day' attitude. I'm in my mid 30s and I am coming to that view. It just seems that what people are willing to do for a quick buck is all too easily tempered by some short term benefit.
So I don't dispute what you are saying about Karma...but I do think that the gnawing rat of guilt probably isn't as strong as you might think and people do what they do and few of them lose much sleep.
