I’ve raised this issue a few times before:
Park attendants being told to question people in parks (especially men) if they have no children
or men in the US refusing to get near children in need due their being afraid of being branded a child molestor whilst in the UK everyone is banned from coming into contact with children without a government permit.

Now the Times asks whether maybe this hasn’t gone a bit far, with especially men refusing to volunteer to do anything having to do with children due to the suspicion and bureaucracy involved.
