One of the best on the subject of Jack The Ripper & The Whitechapel Murders.
For me, the documentaries findings reveal the only true suspect, as any other is pure speculation & nothing more than flimsy circumstantial evidence, such as they lived in the area etc.
The only person actually linked directly to a crime scene, but incredibly overlooked at the time.
I am of the opinion that had he been investigated as a suspect then we would not have the Jack The Ripper mystery to look back on.
