Not the first time. A few years ago, Arab workers at Café Rimon in Jerusalem were apprehended before they could put the same or similar poison in the food. Good police and intelligence work and all but it is stupid to apply the label "recist" to Rav Lior and others who oppose hiring Arabs. The government never tires of telling us that no one can guarantee a 100% result. Note: this time the government is telling the truth! The intel and police folks cannot always save us from our own stupidity. We are simply not smart enough to know which of today's Arab workers will be a terrorist mass murderer tomorrow. That's not racism. That's part of the facts of life.
