My opinion was based on the thought process of the police, maybe at this stage they want to keep it in people's mind's that he could be wearing anything, BUT I've just read he also discarded his shoes and there haven't been any sightings so I think the police are thinking along the lines that he is sheltering somewhere and are keeping their focus on finding out where he went and what happened after the last sighting to avoid getting too bogged down in intel' which they feel might not be relevant - Although it does sound as if they are too focused on the idea he is sheltering somewhere and it's getting to a point where they might need to explore other possibilities and start sharing that footage
What I do find strange is that people have not been actively asked to search their camper vans/caravans, there was a case very recently of a lady who was certain her camper van was secure but nether the less she discovered someone had been living in it for weeks... It might be the obvious thing to do for lots of local people but maybe not if they think they are certain their camper vans are secure..
