Actually the airports confiscate tons of liquor weekly. They have to store it and destroy it under OSHA and other guidelines.
Unless you go for some super high level security clearance it likely won't come up on a typical background check. Customs just needs the paperwork so they can destroy it. Otherwise you could appeal the process.
