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, BATF, 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 their initials in large yellow letters across their backs

"FATASS."
