OK, first paragraph:
An invisible bridge spans the Thames at Blackfriars. Victorian pilings jut from the river, the railway they once supported long gone. Dangling above them on this cold day, helicopters surveilled thousands of strikers and supporters processing loudly through central London. It was Nov. 30, 2011, and two million public-sector workers were on strike.
Besides some very awkward verb choices - surveilled? processing? - he switches tense for the last sentence in a way that would "jut" out to a fucking O-level student.
Here endeth.
