Raising the Flag at the Dept. of Vets

Snapped this pic this morning on the way to work outside the Department of Veteran Affairs. Also of note, this is the same building that I frequently see what I assume to be caught illegal immigrants being led out of white vans, handcuffed, into the building.

This was at the Corner of Varick and King St. I believe that's a POW flag they're raising alongside the American flag. So I ask you, how many NYC employees does it take to raise a flag?
