Well this sure seems like a totally reasonable use of Diplomatic Immunity
The parents of a teenager who was killed in a head-on collision say they are "utterly broken" after the suspect, a US citizen, claimed diplomatic immunity and left the country.Harry Dunn, 19, was killed in an accident near RAF Croughton in Northamptonshire on 27 August. It is an American spy base.
Police told Sky News that their initial findings show that Harry was riding his motorbike on the correct side of the road, but that a woman, who pulled out of the airbase onto the wrong side of the carriageway, hit him head-on. He suffered multiple injuries and died later in hospital.
Sky News can reveal that the suspect is the wife of a US diplomat who claimed diplomatic immunity following the incident.
Harry's family received a letter from the US Ambassador to the UK, Woody Johnson, expressing "profound sadness". In a statement, the US Embassy in London told Sky News: "We express our deepest sympathies and offer condolences to the family of the deceased in the tragic August 27 traffic accident involving a vehicle driven by the spouse of a US diplomat assigned to the United Kingdom.
“Embassy officials are in close contact with the appropriate British officials on this matter. Due to security and privacy considerations, we cannot confirm the identity of the individuals involved, but we can confirm the family has left the UK".
