Where's Wally is a series of children's books created by the British illustrator Martin Handford. The books consist of a series of complex full-page illustrated pictures of hundreds of tiny people doing various illegal things. The purpose is to find Wally among the group, which could be difficult as he is always well hidden.
Where's Wally illustrates the point, if you want to hide a tree, hide it in a forest, a grain of sand in the dessert or a drop of water in the ocean etc.
Accordingly the best hiding place for a false/fallacious argument is in a plethora of irrelevant or incidental arguments. Therefore, if you receive an unnecessarily long winded, overblown and complex looking document full of irrelevant and incidental arguments from a Local Government Ombudsman then take care to look very closely. If there wasn't a 'Wally' in there somewhere they wouldn't need to provide a hiding place.
Martin Handford would have found it impossible to hide Wally if he was the only character on the page just as an Ombudsman would find it impossible to hide a false/fallacious argument in a concise document.
