The persecution of Jews in occupied Poland meant that we could see horror emerging gradually in many ways. In 1939, they were forced to wear Jewish stars, and people were herded and shut up into ghettos. Then, in the years '41 and '42 there was plenty of public evidence of pure sadism.

When there are no avenues of escape or one is caught even before any attempt to escape can be made, then for the first time the use of self-defense techniques should be considered. Even at times like these, do not show any intention of attacking, but first let the attacker become careless. At that time attack him concentrating one's whole strength in one blow to a vital point and in the moment of surprise, escape and seek shelter and help.
