I live in South Florida, I go to downtown Miami for business at least once a week, and I have plenty of friends and business associates who live near downtown.
I have kept abreast of the local developments, and my friends contradict your "Indymedia" sources. Eyewitness accounts and video tapes have shown the demonstrators attacking the cops, and the cops acting only defensively.
I don't expect to get an unbiased opinion from Indymedia anymore than I expect to get one from CNN. I want to hear everyone's side of the story and decide for myself. If you have eye-witness accounts, by all means post them.
This is the beauty of the internet - unfiltered news.
