The siege of Julian Assange is a farce

The siege of Knightsbridge is a farce. For two years, an exaggerated, costly police presence around the Ecuadorean embassy in London has served no purpose other than to flaunt the power of the state. Their quarry is an Australian charged with no crime, a refugee from gross injustice whose only security is the room given him by a brave South American country. His true crime is to have initiated a wave of truth-telling in an era of lies, cynicism and war.

The persecution of Julian Assange must end. Even the British government clearlybelieves it must end. On 28 October, the deputy foreign minister, Hugo Swire, told Parliament he would "actively welcome" the Swedish prosecutor in London and "we would do absolutely everything to facilitate that". The tone was impatient.

The Swedish prosecutor, Marianne Ny, has refused to come to London to question Assange about allegations of sexual misconduct in Stockholm in 2010 – even though Swedish law allows for it and the procedure is routine for Sweden and the UK. The documentary evidence of a threat to Assange's life and freedom from the United States – should he leave the embassy – is overwhelming. On May 14 this year, US court files revealed that a "multi subject investigation" against Assange was "active and ongoing".

Ny has never properly explained why she will not come to London, just as the Swedish authorities have never explained why they refuse to give Assange a guarantee that they will not extradite him on to the US under a secret arrangement agreed between Stockholm and Washington. In December 2010, the Independent revealed that the two governments had discussed his onward extradition to the US before the European Arrest Warrant was issued.

Perhaps an explanation is that, contrary to its reputation as a liberal bastion, Sweden has drawn so close to Washington that it has allowed secret CIA "renditions" – including the illegal deportation of refugees. The rendition and subsequent torture of two Egyptian political refugees in 2001 was condemned by the UN Committee against Torture, Amnesty International and Human Rights Watch; the complicity and duplicity of the Swedish state are documented in successful civil litigation and WikiLeaks cables. In the summer of 2010, Assange had been in Sweden to talk about WikiLeaks revelations of the war in Afghanistan – in which Sweden had forces under US command.

The Americans are pursuing Assange because WikiLeaks exposed their epic crimes in Afghanistan and Iraq: the wholesale killing of tens of thousands of civilians, which they covered up; and their contempt for sovereignty and international law, as demonstrated vividly in their leaked diplomatic cables.

For his part in disclosing how US soldiers murdered Afghan and Iraqi civilians, the heroic soldier Bradley (now Chelsea) Manning received a sentence of 35 years, having been held for more than a thousand days in conditions which, according to the UN Special Rapporteur, amounted to torture.

Few doubt that should the US get their hands on Assange, a similar fate awaits him. Threats of capture and assassination became the currency of the political extremes in the US following Vice-President Joe Biden's preposterous slur that Assange was a "cyber-terrorist". Anyone doubting the kind of US ruthlessness he can expect should remember the forcing down of the Bolivian president's plane last year – wrongly believed to be carrying Edward Snowden.

According to documents released by Snowden, Assange is on a "Manhunt target list". Washington's bid to get him, say Australian diplomatic cables, is "unprecedented in scale and nature". In Alexandria, Virginia, a secret grand jury has spent four years attempting to contrive a crime for which Assange can be prosecuted. This is not easy. The First Amendment to the US Constitution protects publishers, journalists and whistleblowers. As a presidential candidate in 2008, Barack Obama lauded whistleblowers as "part of a healthy democracy [and they] must be protected from reprisal". Under President Obama, more whistleblowers have been prosecuted than under all other US presidents combined. Even before the verdict was announced in the trial of Chelsea Manning, Obama had pronounced the whisletblower guilty.

"Documents released by WikiLeaks since Assange moved to England," wrote Al Burke, editor of the online Nordic News Network, an authority on the multiple twists and dangers facing Assange, "clearly indicate that Sweden has consistently submitted to pressure from the United States in matters relating to civil rights. There is every reason for concern that if Assange were to be taken into custody by Swedish authorities, he could be turned over to the United States without due consideration of his legal rights."

There are signs that the Swedish public and legal community do not support prosecutor's Marianne Ny's intransigence. Once implacably hostile to Assange, the Swedish press has published headlines such as: "Go to London, for God's sake."

Why won't she? More to the point, why won't she allow the Swedish court access to hundreds of SMS messages that the police extracted from the phone of one of the two women involved in the misconductallegations? Why won't she hand them over to Assange's Swedish lawyers? She says she is not legally required to do so until a formal charge is laid and she has questioned him. Then, why doesn't she question him?
