The family of a teenage boy whose death ProPublica investigated has objected to the publication of a surveillance video that documented his last hours.

Yesterday, ProPublica published a detailed account of failings and missteps by the U.S. Border Patrol, in whose custody 16-year-old Carlos Gregorio Hernandez Vasquez died. As part of the story, ProPublica published several moments from a lengthy surveillance video in which Carlos struggles on the floor of his cell and then stops moving. The video, which had not been shared with Congress or the public, contradicts the government’s claim that Carlos was discovered as a result of a “welfare check.’’ It shows that his cellmate awoke, saw his motionless body, and summoned Border Patrol agents.

Hong Kong democracy protesters are hoping for huge crowds later Sunday at a rally they have billed as a "last chance" for the city's pro-Beijing leaders in a major test for the six-month-old movement.

The march comes two weeks after pro-establishment parties got a drubbing in local elections, shattering government claims that a "silent majority" opposed the protests.

But activists say public anger is building once more after chief executive Carrie Lam and Beijing ruled out any further concessions despite the landslide election defeat.
