Answer 1

took thousands of statements but had no computers to handle all the evidence, heavy policing of red light areas and collected number plate numbers, fake geordie ripper threw police off scent, they lost vital info

Answer 2

the police back then, didn't had training on serial killers even less understanding ways to come up with the modus operandi of the killer. Surprisingly, a full understanding of the Ripper's modus operandi was not established until several years ago. Jack the ripper and his victim stood facing each other. When she lifted her skirt, her hands were occupied and was then defenseless. The Ripper seized the women by their throats and strangled them until they were unconscious if not dead. The autopsies constantly revealed clear indications that the victims had been strangled. In the past some writers believed that the Ripper struck from behind when the victims were bent forward, their skirts hiked up their backsides while waiting to engage in anal sex. This is a very awkward arrangement and the risk that they may scream or elude his clutch's makes this unacceptable.

The experts on the case came to the conclusion that none of the letters purported to have been written by the Ripper when in fact the ripper did write some of them. The police also picked up suspects who were butchers and the so. Speaking about suspects, the police didn't even have abundant experience matching signatures or an individual killer. They came up with 5 victims other with 4 and other up to 11 or 14. Others are certain that the killer killed only 1.

At the time of the murders and for the next few years, a lot was written about the murders including some tabloid type books. Most of it is worthless and only helped to set up many myths that have clouded serious attempts to figure out what really happened that autumn in London. Other than memoirs of officers who worked on the case, which is valuable, little else was written until after the first world war. In 1929 the first full length book in English about the Ripper, The Mystery of Jack the Ripper by Leonard Matters, was published. Once more there was growing interest in the murders again in that the Ripper was appearing in both nonfiction works and fictional formats such as Alfred Hitchcock's The Lodger. Cult-like interest, the interest that has really never left, began in the 1950s. Dan Farson did a television show about the Ripper and uncovered a version of the McNaghten memoranda. The first really good books began to be published in the 1960s, such as Tom Cullen's Autumn of Terror and Robin Odell's Jack the Ripper in Fact and Fiction. Interest in Jack the Ripper exploded in 1970 when a new theory was published in which the grandson of Queen Victoria, Prince Albert Victor, Duke of Clarence and Avondale, was accused of being the Ripper. Just like his nemesis in fiction, Sherlock Holmes, the 1970s saw Jack being either paired with someone famous or identified as being someone famous. Back then there was no fingerprinting or DNA. The police use beat cops looking to catch him on the act.
