"Gunsmoke is a quite distinctive smell."

I wouldn't know. So seven people smelled a smoky smell, they knew that guns had been fired, and they analysed the smell as gunsmoke. Cor. Just reminded myself of the scene. I see that police motorbikes were between the cars and the crowd too. Wonder if they were electric ones.

"There was no likelihood of communication between the witnesses listed."

Alleged gun smoke from one shot, fired well away from the crowds on the, er, sidewalk, being dragged in the wake of speeding vehicles was sufficient to convince seven different witnesses that they smelled a gun. Yet they were so far away from each other that they couldn't possibly have colluded. That must have been one hell of a smoky gun.

Just sayin'.
