When critiquing the police investigation during the Jack the Ripper case, it is important to realize they had no high tech crime scene tools at their disposal like our investigators do today. Nonetheless, there still could have been improvements in the investigation. I am not sure it was a good idea to reveal the letters to the public that were sent to the police due to possible copycats. They should have waited to see if more came before revealing it to match all the different hand-writings before there was a chance for copycats to make their move. Also, I feel that the police withheld certain information that could have been significant to the case, for example James Kelly. When he escaped from the asylum, there was no immediate response because the police wanted to keep it under wraps. Why? There was no reason to keep that information from the public. It was probably to save face at the asylum for allowing a patient to escape. No matter the reason, things like that can really hinder an investigation if the public is not notified to be on the lookout. I think as far as the investigation as the crime scenes go, it is hard to say whether or not they did a thorough job due to the lack of technology they had to work with. Of course touching, washing, and moving the bodies was not a good idea but at the same time, the investigators were not able to work with DNA evidence like investigators are today. Needless to say, it is very hard to critique the investigation due to the lack of investigation techniques they had to work with during the murders.
