Who else can they prosecute
If the only images were in his cache (which he claimed to not know about), does that mean that they can prosecute all of the ISPs out there who run transparent caching proxy servers.
I'm thinking orange in the UK (certainly when I last used them, they were called wanadoo at the time), google is another obvious target... I'm sure that they cache some unsavoury images. Onspeed are next on the list. I'm sure there are hundreds of companies who have kiddy porn in their cache without knowing.
On another note, what self respecting male only has 370 pornographics images in his cache? That's only a couple of pages of tgp, or were they not counting thumbnails?
For the record, no I'm not saying that kiddy porn is OK, just that the argument of "it's in his cache so he must have chosen to look at it" is ludicrous. The article gave the impression that he coughed to willfully viewing said images, but not to saving them, in which case he is still scum of the earth, just not for the reasons given.
