The "perp walk" was perfected in the 1980s by a prosecutor named Rudolph Giuliani; the Wall Street "perp walks" are well known and were meant to put fear in the industry.
The first citations for "perp walk" are from Newsday, 4 November 1986, pg. 52, and the Washington Post, 29 November 1986, pg 23. However, the term is much older.
6 November 1976, New York (NY) Times, pg. 19:
The suspect or "perp" (short for "perpetrator" in police jargon) was an armed state probation officer who had gone berserk in his home.
30 October 1994, New York (NY) Times, pg. SM30:
How old is the perp walk?
The term has been used for at least five decades by New York police and photographers, and some experts point to images of protowalks captured long before photography. In paintings of the expulsion from Eden, Adam and Eve are modestly trying to cover their bodies from public view, and the sword-wielding angel's stern expression anticipates the look on a homicide detective walking an accused cop-killer. Other paintings — of Achilles ceremonially dragging Hector behind his chariot, of the Stations of the Cross, of French aristocrats being carted to the guillotine — display elements of the perp walk, although the spectators appear far more polite than the New York press corps is.
