I think it is similar to what happened with Menezes in that when the police realised that someone who was not armed at the time had been shot they concocted a story to strengthen the case for shooting him.
On the day this happened the police rushed out the story that Duggan had fired at an officer . The bullet turned out to be from the marksman and passed though Duggan's arm and lodged in another officer's radio.
In the heat of the moment, that officer may not have realised where the bullet came from. Or maybe he did. It's never been adequately explained how he and all the other officers thought Duggan was armed and shooting when he most definitely wasn't.
The testimony the officers gave to the IPCC was remarkably similar suggesting that they’d colluded in their accounts. That was put to Asst Commissioner Rowley this morning and he didn’t deny it. He just said that the Met might ask officers to stop doing that in future.
I think the officer who shot Duggan may have thought he was holding a gun - in which case the jury was correct.
But he may not have cared whether he was or wasn't, and in that case I don't know what the verdict should have been - perhaps that's why two people delivered an open verdict.
Duggan may have thrown the gun over the fence. The jury appears to have accepted that theory though no one gave evidence saying they saw it happen.
People did say they saw an officer at the boot of Duggan's vehicle. I think it was the marksman who found the gun. He was seen to walk to it remarkably confidently. When asked in the inquest why that was, his answer was roughly that it was a lucky guess. Which, of course, it could have been.
I don't think the police planted the gun in the car. But somehow it ended up over the fence.
