I’m not for sure that Lawende should be trusted. The police rely heavily on his testimony and his eye witness account of Kosminski, however, he described a broad shouldered, stoat man which does not exactly resemble Kosminski. Also, he refused to testify in court that Kosminski was the Ripper. Why would he not want to end the killings? I realize that they were both Jewish and that he did not want to draw attention to the already disliked Jews but there is no reason that he should not have told the police. I also realize that the victims were prostitutes and that not many people cared for them, but still, there was no reason not to tell the police. Lawende seems kind of sketchy to me, so I would hesitate when taking any word from him.
