Almost 150 years ago, President Lincoln found it necessary to hire a private investigator - Alan Pinkerton - for protection. That was the beginning of the Secret Service. Since that time, the federal government has produced an FBI, CIA, INS, IRS, DEA, BATF, etc. Now we have the "Federal Air Transportation Airport Security Service." Can't you see them now, these highly trained men and women in their black outfits with jackets saying across the backs: "F.A.T.A.S.S."
