Actually Haifa isn't as good as an example as you seem to think. Shabtai Levi did try and get Arabs to stay in Haifa while promising that they wouldn't be harmed. Levi might have had the best of intentions but his position was not shared by those with real power who sent the Carmeli brigade in to cleanse the city with orders to 'kill any Arab you encounter and torch all imflammable objects'. Haifa's Arab population fled to the market near the port gate in hope of escaping the attack and were shelled relentlessly by the Carmeli brigade.
