G20 security in Toronto has, if nothing else, dramatized the degree to which the crowd captures the state of things these days. On the cusp of one of the most significant news events in Toronto's (recent) history, I can't help but notice the degree to which citizen documentation has helped us all to grasp the profound transformation of our city for the G20 summit.

And how better to chart this metamorphosis than through whatWilliam Egglestoncalled the "democratic camera?"

What follows are some of the best -- or, at least, my favourite -- images from theblogTO Flickr poolthat highlight the various security preparations for the G20.

As the summit (and the protests) get underway, we'll be sure to roundup more examples of the excellent journalistic work that our readers share with us.
