Recent cases in the UK where firearms have been used by the police have called into question the veracity of Police statements which have been shown by later analysis to be not true accounts of the situation.
British police officers have been allowed to confer (collude) in order to present one coherent picture of an incident, but given human nature, the accounts given are defensive and self serving.
Juries at inquests (few police are ever prosecuted for illegal gun use- they get a massive benefit of the doubt) are usually quite sympathetic to the problems of policing violence with guns, but have been getting more suspicious of some police accounts, calling them into question in narrative verdicts if not actually finding for unlawful killing.
Armed officers are threatening a two pronged action (they did this in the Met after the Menezes case). They are saying that if they are required to give individual statements they will only give “no comment” interviews, and that if they are ordered to give statements they will resign from the Firearms unit (regular police do not carry firearms.)
Quis custodiet ipsos custodes.
My view is that any professional who is required to do something risky as part of their job should be willing to give account for their actions.
It is a widely held police belief that only the guilty give No Comment interviews- what does that say about their trust in the system that they are paid to uphold if they insist on non-cooperation?
