Photos: 3rd year since Iraq invasion marked with protests.

Protests commemorating three years since the US-led invasion of Iraq are documented in photo streams at Flickr and other image-sharing sites. Relevant tags include antiwarprotest, march20, peacemarch, and of course, Iraq.

Shown here, Matthew Bradley's photos of a protest yesterday at the Pentagon. Link. (Thanks, Arnold Edmayer, spotted on DCist).

Below: found on Flickr under the "iraq" tag and shot by Daniel Ross -- evidence that Cartman was here.
