Late last year, activists attacked websites belonging to companies that refused to do business with WikiLeaks, an online group that has disclosed classified U.S. government documents.
When the activists, who called themselves Anonymous, found out it was being investigated by the Internet security company HBGary Federal, it hacked the company's servers and stole thousands of private e-mails. And then it dumped them onto the Internet.
It was an embarrassment for the security company to get hacked — but the content of some of those e-mails is raising concerns.
Ten days after the Mine Safety and Health Administration (MSHA) reported its working theory about the deadly Upper Big Branch coal mine explosion, mine owner Massey Energy presented its latest findings Friday to reporters and the families of the 29 miners killed.
"Our conclusion to date is different," said Massey Vice President and General Counsel Shane Harvey.
For four hours Tuesday night, investigators from the federal Mine Safety and Health Administration (MSHA) laid out their working theory about what happened April 5, just before a West Virginia coal mine exploded and 29 miners were killed.
They went through the explosion scenario step-by-step in an MSHA auditorium in Beckley, W.Va., filled with relatives of the victims, some weeping at times at the painful implications of the evidence.
NPR News has learned that safety systems were not working properly before that blast at the Upper Big Branch coal mine. Some mine safety experts believe these water-based safety systems might have helped prevent the blast if they all had been working together properly. Host Scott Simon speaks with NPR's Howard Berkes about new developments in the investigation of last year's coal mine explosion.
