This time organizers with the Occupy Chicago movement have planned a morning march on Boeing's building on the Chicago River in protest of the company's role in supplying planes to the US military, the AP reports. Later, immigration rights activists will hold a demonstration south of the city against a planned illegal immigrant detention facility. Overnight police gradually released at least 20 of the 45 people arrested yesterday, with each release drawing cheers from a crowd of gathered protesters, the Chicago Tribune reports. Just after midnight 80 protesters were gathered around police headquarters, and about 30 were still camped out there in the predawn hours this morning awaiting more releases. One of those freed was a freelance photographer who was shooting for Getty. Several police watched over the proceedings from behind metal barriers; as he left, one protester said to them, "See you guys tomorrow." Read These Next Her blood isn't compatible with anyone else's.
