Parasitic round worms are frequently found in the guts and in the flesh of fish. Although only a small proportion of fish sold to the public is affected in this way, the worms are unsightly and consumers naturally object to their presence.
J. Edgar Hoover was the first director of the FBI. He introduced fingerprinting and forensic techniques to the crime-fighting agency, and pushed for stronger federal laws to punish criminals who strayed across state lines. He also kept secret files on more than 20,000 Americans he deemed subversive.
Hoover also sparred with subsequent attorneys general and more frequently became a target of the media. He died on May 2, 1972, at age 77 in the midst of controversy stirred by allegations of illegal FBI activities. J. Edgar Hoover served for nearly 50 years under no fewer than eight presidents, from Calvin Coolidge to Richard M. Nixon. It is because of the Hoover tenure that subsequent FBI directors were limited to 10 years in office.
