I am researching in an attempt to locate video evidence of Imette's St. Guillen's attacker -- using webcams, traffic cams and security cameras around Manhattan, Queens, the Belt Parkway and Brooklyn. Since I am not a New Yorker, and know little about the city, I have questions that readers may be able to assist with.

1) Are there traffic cams with archives at ANY of the following intersections?

Lafayette St. & Kenmare
Delancey & Bowery
Delancey & Allen
Williamsburg Pkwy & Pitt St
Williamsburg Pkwy & I-278 interchange
I-495 & Grand Central Pkwy E interchange
Grand Central Pkwy E & Jackie Robinson Pkwy
I-678 & ramp to Kennedy Airport
Springfield & Belt Pkwy E interchange
Belt Parkway E/W & Van Wyck Expy
Belt Pkwy W & Nassau Expy interchange

2) Are there image archives from the mta.info website's Queens Midtown Tunnel traffic cam that might be available for early morning Saturday, Feb. 25th?

3) Does the Aqueduct Racetrack have cameras trained on the Belt Parkway West? If so, were they active this past Saturday afternoon during the horse races? If so, can one clearly see the Belt from these cams?
