This is not going to stretch new york s hospital systems in the way that obviously 9/11 did or the boston marathon did here. and they will continue to help those who are hopefully continue to be in good condition. and now the investigation will be both foreign, are there any ties? do they know who the suspect is? and what is that footprint in terms of physical and internet? i want to say one thing. all of the training i ve ever done or led on mass transit attacks would have had the system shut down, immediately. and i what is going to be very interesting to review is what happened at that moment in terms of where the suspect was able to go and how he was able to escape. that s i don t blame anyone in the moment of something bad happening, but it is going to be a lesson learned, because that is what you do when a system is attacked. you shut it down and how the perpetrator got out is unclear.
