 In May 2010, WikiLeaks said it had video footage of a massacre of civilians in Afghanistan by the US military which they were preparing to release.In an interview with Chris Anderson on 19 July 2010, Assange showed a document WikiLeaks had on an Albanian oil-well blowout, and said they also had material from inside British Petroleum, and that they were "getting enormous quantity of whistleblower disclosures of a very high calibre" but added that they had not been able to verify and release the material because they did not have enough volunteer journalists.In December 2010, Assange's lawyer, Mark Stephens, told "The Andrew Marr Show" on BBC Television that WikiLeaks had information it considered to be a "thermo-nuclear device" which it would release if the organisation needs to defend itself against the authorities.
