>> Mass shootings, chemical attacks, suicide bombings, even planes flying into buildings, Las Vegas has spent years training for the worst events possible. But when Stephen Paddock started spraying a country music festival with bullets from his room on the 32nd floor Police here found themselves with few options to quickly stop him.
Reuters correspondent Tim Reid has been talking to counter terrorism experts on the ground to understand why.>> The police counter terrorism squad here told me that they had the weapons with the range to fire back at the shooter. And normally, in their protocol the first thing you do is aim fire at the shooter's location.
However, they were not able to do that, because they were gonna be firing bullets into a hotel from a low down range. The bullets would go up through the room and into rooms above the shooter. And so they were worried that they would kill Innocent civilians.>> Las Vegas police in 2009 adopted a new military style counter-terrorism plan and training called MACTAC.
Alarmed by the 2008 attack in Mumbai, India, where Al Qaeda linked militants killed 164 people in a series of coordinated shootings and bombings over four days. Las Vegas also has sophisticated surveillance technology that can detect if someone tosses out a cigarette butt from their hotel balcony. Although as the Mandalay Bay didn't have balconies or windows that opened, it wasn't used.
Cameras that canvass the Las Vegas strip also did little to help put police on to Paddock.>> One of the Councilmen I spoke to said that they have protocols in place to try and screen out potential gunman or terrorists. He didn't fit into any of those and so he came from nowhere.
>> Las Vegas is now considering whether it should install metal detectors at hotels and casinos. Machines that would have tipped off police about the 23 firearms Paddock brought up to his room.
