Lawmakers were sharply divided over the police shooting which killed an Israeli Arab youth in Kafr Kana late Friday, setting off unrest in the Galilee.MKs on the Right said the police officer's response was justified, while some on the left called it murder.Economy Minister Naftali Bennett said: "A crazed Arab terrorist attacked a police car with a knife, in an attempt to murder the officers inside. The officers' reaction is what is expected from our security men."This is not a murder in cold blood and we certainly should not abandon the people who are sent to defend us," he added. "If we do not back them, more and more Israelis will be murdered by knives, firecrackers and vehicular attacks."Still, Bennett said such incidents must always be investigated.Construction Minister Uri Ariel blamed the attack on the government's policies in Jerusalem, positing that "whoever believes in containment in Jerusalem will, in the end, have to deal with terrorism in Kfar Kana."Ariel called for Prime Minister Binyamin Netanyahu to change strategies and instruct security forces to go from containment to the offensive to eradicate Arab terrorism.
