dispel uv confusion. Donerf (details here) is not difficult. It is enough just to remember (naturally, adapted to a certain reality) the recommendation of a friend. Lasis:
"We are not waging war against individuals. Do not look for materials and evidence that the suspect acted in deed or words against the authorities. The first question we must ask him is to which class he belongs, what is his origin, upbringing, education or profession. These questions should determine the fate of the suspect."
