I dunno. Maybe maybe not. If it's looking for the shine from a lense, I don't see how it can tell the end of a scope or binocs as mentioned from an eyeglass lens.

There appear to be two devices/detection capabilities being discussed here: An acoustic one to locate the source of a fired shot, and a laser one to locate the shine off of optics. I guess this latter can tell the difference between a flat piece of glass and a shaped lens.

I must assume that if this is getting print today, the USSS has had it for years.

Bingo! The was one of the obvious thoughts about this - how long has it been deployed already? How long was the F-117 around before they became widely known?

It would have to be a little more sophisticated then simply aquiring a shine....otherwise they'd be blowing out everyones house, business, car windows.
