Lots of wildlife offences were committed on the Sandringham Estate that the police have been prevented from properly investigating.
"A Guardian investigation has revealed that dozens of UK laws stipulate that police are barred from entering any of the Queen’s private estates without her consent to investigate crimes ranging from wildlife offences to environmental pollution – a unique privilege not granted to any other private landowner in the UK.
In fact, a year before the shooting incident in the vicinity of Sandringham, the UK’s wildlife legislation was updated. The Natural Environment and Rural Communities Act 2006 included amendments to a number of laws for England – one of which sets out the Queen’s personal immunity from prosecution for wildlife offences, and denies wildlife inspectors the power to enter her private estates to investigate alleged crimes.
But internal documents from Natural England, obtained by the Guardian, reveal that Sandringham has been the focus of successive police and regulatory investigations.
Sandringham has been investigated for wildlife and pesticides offences against legally protected birds of prey at least six times between 2005 and 2016.
As well as the two hen harriers shot in 2007, police and Natural England have investigated the deaths of a goshawk, a sparrowhawk, a red kite, a tawny owl and a marsh harrier at Sandringham estate and land it owns nearby, with only one prosecution.
In 2009, the estate was given an official warning about the mishandling and unlawful storage of highly toxic chemicals after the sparrowhawk was poisoned.
In 2016, Sandringham admitted it had destroyed the body of a goshawk found dead near Sandringham House before it could be examined by police, which meant no cause of death could be established."
