forward throughout the day. there are about 150 rental truck agencies throughout the new york city area that apparently starting two years ago the nypd is saying they went to all these rental agencies and told them to look out for certain indicators. indicators of those who might be up to nefarious means. clearly this is one of them. what signs did they have? we don't have answers on that. could they have been tipped off? we don't know that just yet. we're waiting on those answers so far today. u haul, rider, home depot. when you think about the christmas attack in berlin and the a tack in nice as the crowd of thousands were moving away from the fireworks display and the terrorist killer was coming the other direction with a several ton refrigerated truck trying to hit as many people as possible in his way.
