How realistic was it for JTR to disguise himself as a PC?

[Sam Flynn]

Dorset Street in 1960. In 1905 it's name was changed to Duval Street.

Thanks, but Miller's Court isn't in that photograph. I was referring to the original Dorset Street.

[Simon Wood]

Quite so, Sam. Miller's Court was torn down in the late 1920s. However, Crossingham's lodging house might be among those buildings on the opposite side.

Maybe the unknown/untraced PC, George Hutchinson reported his sighting of Astrakhan man to was really Jack? I think I'm on to something here...

I would have thought very possible indeed. Of course he could have disguised himself as a PC. It's a good theory.
