Marc Sageman, a forensic psychiatrist and former CIA officer who has testified to discredit Kohlmann‘s claims, described his testimony and reports as „so biased, one-sided and contextually inaccurate that they do not provide a fair and balanced context for the specific evidence to be presented at a legal hearing,“ according to the Intercept.
