The jury ruled that London thugs lawfully shot Mark Duggan.

It's possible that the thugs really believed Duggan had a gun. It's possible he did have one, in the box. It's possible the thug who shot Duggan really believed at the time that the gun was in his hand. These are not implausible.

But it seems clear that someone other than Duggan put the sock-covered gun on the other side of the fence, and the obvious suspects are thugs trying to make the shooting look justified.

I think that calls for its own investigation.
