It isn't a crime? You should explain that to the Bail Act 1976 (http://www.legislation.gov.uk/ukpga/1976/63/section/6 http://www.legislation.gov.uk/ukpga/1976/63/section/6) amended by the Extradition Act of 2003 because they believe: "A person who is convicted summarily of an offence under subsection (1) or (2) above [which outline not attending without good reason] and is not committed to the Crown Court for sentence shall be liable to imprisonment for a term not exceeding 3 months or to a fine not exceeding level 5 on the standard scale or to both and a person who is so committed for sentence or is dealt with as for such a contempt shall be liable to imprisonment for a term not exceeding 12 months or to a fine or to both." The court and / or the CPS may view that there is no public interest in that, though similarly they may view given the cost to the tax payer of the round the clock surveillance of the embassy he should be made an example of. I'd be inclined to believe the later.
