I've done a piece today for Index on Censorship about Atif Amin, the customs investigator who is being investigated by the IPCC (yes, really, the Independent Police Complaints Commission) over allegations that he broke the official secrets act.
He isn't a whistleblower in the true sense of the word as all he did was comment on information that was already in public domain, that he was prevented from investigating the A.Q. Khan nuclear smuggling network after he found that it was smuggling proliferation-sensitive materiel to Libya.
As I commented in an Independent Minds blog, what seems to have upset the state is that he (very mildly) questioned whether it was a good idea to watch Khan proliferating for a further three and a half years. During this time the network supplied Iran and caused Tony Blair so much worry that he invaded Iraq.
So why is the IPCC investigating Amin and questionning BBC journalists, while the killers of Jean Charles de Menezes get away scot free - not to mention the proliferators?
