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, federal police authority has grown to a large number of multi-letter agencies - FBI , CIA , INS , IRS , DEA , ATF , etc.
Now comes the Federal Air Transportation Airport Security Service . Can't you see them now? These highly trained men and women in their black outfits with initials in large white letters across their backs?
F. A. T. A. S. S. - - - - - - - I feel safer already.
