How effective were the Victorian policing with the case of Jack the Ripper.?

They did not have the modern resources for detection.

Have you tried these sites

1 The City of London Police at Wood Street have a museum and website with lots of material

2 The murders actually took place in what is now the London Borough of Tower Hamlets - try the borough archive website.

3 Visit the 1888 Whitechapel Society site - Ripper specialists

4 http://www.casebook.org/ another Ripper club

5 Jack The Ripper Forums http://www.jtrforums.com/

There are others - and if any sources look too similar you might need to look for additional ones to get a good spread.

BBC America showed an excellent film on Jack the Ripper that gave what I think is the best theory as to his identity. (He was a German merchant sailor who esceped to America and committed similar crimes there.) The film also shows how the press and the inadequate police work hampered the case in England. Bilbo is right, however, in that the police simply didn't have the technology to handle a CSI properly.
