All knife crime should be prosecuted and punished with the utmost severity. It is irrelevant if the victim is a Jew, Arab or Foreigner. Anybody who leaves their home armed with a knife should know that they will face harsh punishment. If they choose to stab someone, and the victim dies, the charge should automatically be murder. A knife is a lethal weapon - if you carry one you are by definition prepared to kill.
