Sure, Dakata, but my point is we do not know what the guy was sentenced for, or what the assault was -- it's not, in fact, clear to me from the commentary whether the assault was a sexual assault at all, or an unrelated matter that was only concientally associated with the cache of images for which he fell to be sentenced.
Nor do we know the jurisdiction -- what state it was, or even what country it took place in. It could well be the USA but the reference to his buying breakfast at Tim Horton's suggests it may well have been Canada. So we don't know what the sentencing regime is, or how consistently it's applied, or anything.
Quite possibly, as you suggest, it may have been an unduly lenient sentence. Certainly it happens sometimes in the USA, though equally certainly US sentences sometimes seem, at least to me, unduly harsh. I remember one case in which I was involved some years ago, where a group of men exchanging unlawful images were prosecuted, some in the USA and some in the UK. The ones in the English courts ended up with sentences ranging from about 5 to 10 years, while their American counterparts were receiving terms two or three times as long for very similar offences.
So the sentence may be unduly lenient. It may be spot on. I don't know, and neither do you, and neither do the guys who made the YouTube video. We do know that the Parole Board will have had the advantage of knowing the details of the offences, and will have had access to pre-sentence reports and reports on the man's progress and conduct in prison, and that they made the considered decision to release him on licence.
I don't know if that was the right decision or not, but I do know that the Parole Board, knowing what the case was about, were better placed to make that decision than am I or than are those two YouTube chaps.
Certainly the man's behaviour seems, on the face of it, quite alarming. The woman whose child he photographed seemed very concerned and, quite rightly, reported the matter to the police. That's what the two YouTube guys should have done, too, to my mind, if they were really concerned about his behaviour rather than playing at being detectives in order boost their channel.
The police and the probation service (or whoever is in charge of post release supervision wherever this happened) will certainly be concerned, and the stuff in the man's car may well provide the probation service with a good reason to recommend his return to custody. Or there may be a perfectly innocent explanation for it all. I don't know, and I'm not going to waste time wondering -- the police are best placed to investigate that. Which is why I think the two young men should have gone to the appropriate authorities rather than putting their exploits out on YouTube.
