While Vern Edwards disagreed with my bold assertion http://www.wifcon.com/discussion/index.php?/topic/2516-delivery-order-against-a-gsa-bpa/ (see post #11), looks like GAO agrees with me:

My fave from the referenced Post Vern's Post # 15 "As for your protest speculation, who cares? I can come up with solutions to all of your concerns while making coffee in the morning half asleep. What do you think procurement is -- rocket science?"
Well, apparently the FBI should have cared. Perhaps they should have consulted with a Rocket Scientist. Kudos to them for trying. I AM a fan of such innovation, however, as I speculated, such an order instrument would not withstand a protest and indeed it did not.
