Ok so possession of explicit material is not funny in the slightest - but the story does take a more purring turn.
The report said: "According to a sheriff's report Friday, Griffin told investigators that his cat jumped on the computer keyboard while he was downloading music. He said he had left the room and found ‘strange things' on his computer when he returned."
As unlikely as this sounds, there is likely to be some level of sympathy for Griffin if it transpires that he was telling the truth. Unfortunately for him, it is unlikely to be the case considering that the chances of a cat entering a URL, credit card details (possibly) and downloading the images are slim to none.
If it was the case that Griffin already had a page open with images ready to download, and the cat leapt on the enter button could that be perceived as a crime? Surely that would depend on viewing (rather than downloading) is considered a crime or not in that particular state.
Either way, it would be a shame if the cat were held responsible. It would of course be a Security Cat.
