So there is at least at some level some official capacity for kilts in some U.S. law enforcement units. I just came across these photos taken at the 2009 National Honor Guard Demonstration. Both U.S. Customs and U.S. Border Patrol wear Ike jackets that are unbuttoned. The USBP honor guard wears a different jacket, which would have been nice to alter into a patrol jacket, but the pipe band wears the Ike jacket instead (which requires no alteration). The piper(?) for Springettsbury Township in the last photo is wearing an altered version of their honor guard's jacket, which looks nice though I'd like it better outside the kilt with the belt worm more like on a Montrose doublet.
