These house searches typically took place from 6 am and often lasted during office hours for 1 to 3 hours. In many cases, doors were broken down, and there were reports of inappropriate treatment of those affected. One example is Rolf Kron, who had to endure sitting in his nightgown with an open door for hours in the winter. Physical violence was also a concerning issue: Dr. Woitzel had to undergo a leg amputation due to police violence.
