So the US Gub'mint is asking a Member of the Scottish Parliament (MSP) to attend an inquiry into conspiracy theories that the release of the (almost certainly innocent) Mr Al-Megrahi was a result of a BP oil deal with Libya.
Now when I last looked, Scottish MSPs are elected by Scottish voters, not US Citizens.
Obama is clutching at straws in implying that the Gulf Leak is a British problem, (despite the root cause being Cheney's Halliburton cowboys), when BP is a global, multinational conglomerate formed from a merger between British Petroleum & AMOCO.
So if USA can subpoena MSPs about Libya and BP, can UK subpoena Dubya and Rumsfeld about the illegal detention of UK Citizens at Camp X-Ray in Guantanamo Bay?
