I am willing to bet Chicago isn't the only city with these black sites.

I think a protest at Homan Square is good - but I think a large protest at Lincoln Park or another visible city venue would be good as well. Plenty of ways to assemble and visible to the population.

I have a feeling the internet is going to bring justice down on them hard.

It's just a shame that we can't have any protests in real life, anymore. I understand that many can't go to them, but this is Chicago we're talking about, which is a very big city. Let's hope lots of people will go and have a peaceful protest.
