Jack The Ripper was never caught.
Police did not possess the tools needed to catch this type of killer. The science was just not there. It had nothing to do with conspiracies involving the royal family or Scotland Yard cover ups, the Ripper case needed modern forensics.
Catching criminals was the job of Scotland Yard's police force. When the Ripper proved uncatchable of course police were criticized for 'letting him get away.' Most people don't know that the police tried very hard in their pursuit of the Ripper. They just did not possess the knowledge and tools needed to catch the type of killer the Ripper was. Chances are very good that Jack would have been apprehended had the police had modern crime solving techniques.
To be the very best that noone ever was. To catch them was his real test, to train them was his cause.
They argued because Thomas Edison was supporting the electric flow of direct current, whereas Nikola Tesla wanted Alternating current to catch on. Today, we generally use alternating current.
Scotland Yard never claimed to have captured Jack The Ripper and in fact were ridculed for their inablity to catch him. It resulted in many conspiracy theories, some involving the royal family, the police force and even Inspector Fredrick Abberline.

Jack the ripper was the first serial killer to reach the media. The world has eyes on him. It was a scandal about the condition the police was at that time. There were no false starts in this case. There was nothing to go on but the remains of the victims. Even today it takes quite some time to catch a murderer on the run, but in the case of Jack the Ripper, there were many aspects police today would not come across.
The serial killer from London's Whitechapel district in the late 19th century gave himself this name in letters sent to the Metropolitan Police at Scotland Yard, and to the local press. It is not uncommon for serial killers to correspond with police in a risky game of cat and mouse. The goal, to prove he is smarter that those who are trying to catch him, namely, the police.
They printed up fliers, added extra police to patrol the streets of the East End, but the technology was not advanced enough to catch him. Nobody that has done any research into the crimes of JTR can say that Scotland Yard did not try their best to catch the man. There were many in law enforcement, from the lowest "bobby" to the highest detective, that put 110% into his capture. Unfortunately, the Victorian era did not have the science yet to catch a killer of his sophistication. I'm sure Abberline went to his grave with feelings of frustration at not being able to apprehend the biggest case of his career.
they didnt find him because the methods they had of finding people in those times were not advanced enough and he did not leave any evidence behind at crime scenes
