We still lack an explanation for why he wore a heavy coat in the middle of the summer, any why he jumped the turnstile. Not capital crimes, but it's almost as if he wanted to be perceived as a terrorist.
Why do we need an explanation? Every time I walk down my crowded local High Street I see a few people who are unseasonably or otherwise eccentrically dressed (and that isn't just teenagers, for whom the concept of the passing seasons doesn't seem to exist in this age of central heating and air conditioning.) I know several elderly gents who persist in wearing short trousers throughout the winter. There could be a thousand plausible reasons for his wearing a heavy coat. We don't have an enforceable public dress code in this country, thank goodness.
