Ben, yesterday's Crikey.com.au ezine had a different take on your so-called 'gestapo arrest on the jaywalker'. Unfortunately it's only available on their (paid) subscription website, but I'll include a few quotes from the article:
"How accountant and jay-walker Greg McLeay was arrested at APEC
A first hand account by an anonymous Sydneysider
I saw the arrest of Greg McLeay happen first hand, start to finish (well, not including the underground bit)."
"This dude fully brought it on himself, I'm no real fan of the cops (thanks to being done speeding at 5.20am on the way to work), but they handled this well considering the tension in the air around APEC. "
"I read the news article just this morning, and am struck by the differences in what 'happened', and what I saw."

(You can apparently sign up for a free trial subscription which presumably will give you access to the full article?)
