Incidentally I think that Mr Cop "rating them up the green" probably means chasing them off with loud scolding.
I imagine "rating" is like "berating"
I took it to mean that too, and "green " would be a grassy area, as in 'village green'. There are quite a few archaic words in it, but even if they were replaced with the modern equivalents, I'm sure it would still make my brain hurt.
I think a convoluted sentence is harder work because your brain has to grapple with the structure, but with stream-of-consciousness there isn't really any structure, it just floats past you.
