Aye, I read some time ago about only certain digital cameras being used in the US as their courts require some kind of hash/checksum thing to prove that the image hasn't been tampered with - and only somtehing like the 1DS did it back then. Can't remember what it was called though :(
I initial instinct was a D90, but there appears to be a ~45° angle on the viewfinder/flash bit, which seems to match the D3000.
But looking more closely, the button to the left of the LED does look more like it's where the D90's info button is compared to the D3000's delete button.
If I see a Mr B 610 wandering around I'm gonna ask him. :)
