Namely, the NYPD is taking a cue from the U.S. military and is considering adding an unmanned drone fleet to this arsenal. I will bet that this fleet won't be looking for foreign insurgents or enemy terrorists in NYC. It is more likely that these drones "that can shoot live missiles" will be patrolling for NYC residents or perhaps even "enemies" of the State. The video also explains a little about the proposed drone program.
In a recent email obtained through the Freedom of Information Act, an NYPD Detective in the Counterterrorism Unit asks the Federal Aviation Administration about the use of drones as a way to protect the city.
