The UK is full of these public decency laws that have a lot of vagueness to them, meaning they can be broadly applied even in situations where they shouldn’t (not saying this is one of those situations, this guy did more than just stand on a roof).

The ridiculous thing is that “making a youtube video” or something similar could potentially be considered a “reasonable excuse”. Probably easier to get away with it if you’re a network TV show, at least that’s generally been the case over the last few decades…
