He was what we would call 'mentally challenged' and thus ended up on the list of suspects. I find it very difficult indeed to believe that he could have been clever enough, AND had the knowledge of anatomy that the Ripper had.
Kosminski had appeared as so mentally compromised by mental illness by 1891 when he had been finally institutionalized permanently, but that doesn't mean he had been in that frame of mind when the Ripper murders were taking place. It's actually not so uncommon for serial killers and other psychopaths to disintegrate so completely after a few years if they are not able to find victims, especially if mental illness is involved. Back when I was a kid, Spokane had had the South Hill Rapist, AKA Kevin Coe, who had come across as cool, manipulative, and calculating. And yet, after he had been convicted and sent to prison, when the realization had dawned on him that he no longer had women to sexually prey on, he suffered a mental breakdown. Kosminski had been sent for shorter intervals to work houses and an asylum between his identification as Jack the Ripper and his final incarceration, during which time he was being closely watched by the police, and he apparently
knew he was under watch, which would have made committing terrible murders and mutilations impossible, and would have been a living hell for him. The fragile string holding on his mask of sanity would have broken, causing said mask to eventually and permanently fall away. My point is, the street person who ate garbage off the street because of his paranoid fear of eating food given to him by other humans, who had auditory hallucinations, and who refused to speak English anymore, was probably not always who Aaron Kosminski was. In fact, that he had only a few years before worked as a barber reveals that his mental state had been considerably healthier at one time.
