Kilted cops at the 9/11 Memorial

This is the only pic I could find that had anything in it. You can see the pipers in the back.

Was it this:

New York City/Tunes of Glory tartan,

or this one: New York Fire Department Pipe Band?

The NYPD has their own tartan as well, but it's more gray than blue.
