Really. What will implementing this system really do in regards to preventing or combating terrorism? Once completed, this system crosses a section of Manhattan off of a very long list of possible U.S. targets, effectively detouring any possible attacks to, say, L.A. Or it might end up being Chicago. The point is, if we are going to be attacked, terrorists will already know where NOT to attack. If this system is effective in preventing, it will simply be avoided and another major U.S. city will be targeted.

Now the only way this system will be truly effective is if it is implemented in every major U.S. city, which is quite a costly proposition terms of both national funds and individual privacy (Hello big brother...). So, when you get down to it, this system is either a pointless waste of tax dollars that has been engineered to make the public feel secure in that the government is doing something to protect them, or it is the first stepping stone to a frighteningly widespread surveillance network. Either way, no thanks.
