In reply to abr1966:
Speaking with my parental hat on, I think I would be rather more concerned about a 50 something man waiting outside a school to talk with the kids, than with a one-off event of him walking past the school naked - especially given that it was quite apparent from the film (although, granted, it would not be apparent to parents/children at the school, hence the complaints) that the arrival at the school at leaving time was entirely coincidental.
With your child protection hat on (and kudos to you BTW), which would concern you more ?
Another unrelated point... Much mention was made of him not having seen his kids for 6.5 years. To be fair to the fella, he had been in prison for those 6.5 years, so it probably didn't have that much to do with his preference on the matter, and he did see them as soon as he made it 'home'. As to his professing that the lack of contact was worth it in order for him to persue his cause, I suspect that as he had made this cause his life's goal, he would have to admit to his life being utterly pointless if it (his cause) was not worth the sacrifice. He was also separated, and so his contact with them would have been limited to an extent anyway. I suspect that highlighting this was largely an editorial decision, and you would need to spend more time talking to him face to face to get the real picture. Even then, he didn't seem the most articulate of men, so it still may not be apparent what his view actually was.
But then I'm probably over-thinking this all, and projecting my own hangups onto the program.
