This doesn't bother me at all. And if these are like the existing cameras, anybody can link to them via the Internet. Came in very handy during the Republican convention, when I had to be in the office on the weekend, and the leftists were threatening to march through an area very close to my office, that the police had declared off limits, to an illegal mass demonstration in Central Park. I could check what was going on in the streets before leaving the office, to make sure I wasn't going to find myself tangled up in a violent mob scene. The leftists' planned civil disobedience didn't really materialize (sort of like their planned mega-protests this past weekend), but if they had, I could have monitored the situation from the safety of my office, and waited until the streets were under control before venturing outside.
Of course we should be vigilant, and if we detect any abuse of the surveillance camera network, we must raise a massive ruckus. But I'm not interested in hamstringing our law enforcement agencies by declaring them guilty before they've done anything wrong. Keep in mind that al-Qaeda operatives are perfectly free to set up a similar network in the city. There's no shortage of tall, strategically-placed buildings where anyone can rent or sublet an apartment.
My opinion is that one could also learn about traffic jams and mass demonstrations by listening to the radio, watching TV, or accessing sites like FoxNews.com for updates. That should provide more than enough information to make a decision about one's evening commute home on trains, buses, and ferries. This prevents us from having to contend with statist abuse of the camera network, which would be a bundle.

The downtown and financial districts of all big cities are blanketed with cameras already.
I can't imagine a square block in business areas in Manhattan that isn't already covered with cameras.
