Via BoingBoing:

A Hong Kong computer programmer who had legally resided in the US for 15 years (since he was 17) and fathered two American children went for his final green card interview and was locked up, detained until he died of cancer that the DHS refused to treat him for. […] In detention, his complaints of excruciating back pain were treated as fakery, and he was dragged around in shackles after he lost the ability to walk, taken on long, bumpy drives while official demanded that he drop his immigration appeals. The jailers who caused his death were private contractors with fat deals with the DHS to lock up immigration detainees.

As he lay dying, his family — wife and two children, aged 1 and 3 — were denied access to him while the warden considered their request to visit.
