You are sent back in time to September 10th 2001 as a policeman living in New York City how do you utilise all resources and your own limited influence to try and save as many people that you can that are going to die tomorrow?

That's such a heavy "what if" scenario to even think about. Honestly, if I were suddenly dropped into that position, the biggest challenge wouldn't just be knowing what's coming, but getting anyone in the NYPD or the Port Authority to actually listen to a beat cop claiming to have foresight. I'd probably start by making anonymous, specific bomb threats to the building management and local precincts late that night. It sounds reckless, but if you create enough of a security headache, you force an evacuation or at least a lockdown that delays everyone getting to their desks.

If that didn't work, I’d try to pull the fire alarms in the towers early the next morning. Even if people think it's a drill, just getting them out of their offices and into the stairwells or the lobby saves precious time. It’s frustrating because no matter how much you try to scream about the danger, you'd likely just be brushed off as a nutcase or someone trying to cause a panic. You'd be fighting against the bureaucracy and the disbelief of everyone around you, which is probably the most tragic part of the whole mental exercise.
