Some stories are trickling out of Guadalajara about violence towards protestors, brutal treatment in jail. The BBC article referenced here
http://www.democraticunderground.com/discuss/duboard.php?az=show_topic&forum=102&topic_id=590020 seems to hint that no one knows what the protests were about.
The Indymedia sites aren't doing a much better job of explaining it, at least not to people who don't speak Spanish. Some of the coverage has English translation but much of it does not..so any Spanish speakers who can help, please do so.
Some pretty dramatic photos
Can DUers help expand this story? The radio reports on KPFT about the protest and the arrests have been limited, but it seems that there are some brave poor people putting themselves on the line, without much protection. It would be helpful to flesh out this story, if we can.
