A few scientists are dedicated to researching mysterious unclassified beasts which other scientists refuse to believe exist. While these cryptozoologists keep an open mind about their object of study, they are quick to point to cases in which the skeptics were proved mistaken. For example, the pygmy hippopotamus, once claimed to be extinct, was found to exist in East Africa. The giant squid was dismissed as the product of an overactive imagination until a specimen was washed up on a beach in 1873.

        One of the most intriguing mysteries being investigated by cryptozoologists is "Bigfoot," a large hairy humanoid creature which many people claim to have seen in parts of North America. In 1967, a film of Bigfoot was actually taken by an amateur photographer. Some scientists are convinced of Bigfoot's existence, while others argue that Bigfoot is just an elaborate hoax.

      The Loch Ness monster provokes similar disagreements among researchers. In this case some scientists argue that while some creature may have been seen, it is probably a type of whale which penetrates the loch when the Ness River floods.

           The Yeti of the Himalayas may be the most fascinating undiscovered creature. Many climbers claim to have seen the Yeti or its footprints, and local inhabitants of the mountains are convinced of its existence. Such well-known mysteries as the Yeti and less well-known mysteries as the Congo dinosaur and the Queensland tiger will no doubt be the source of much speculation for years to come.

The passage mainly discusses

Investigative work in particular has made great progress during this century.* Laboratory research first played an important role in the 1920s, when evidence from the scenes of violent crimes began to be systematically collected and examined for the purpose of identifying perpetrators.* This work was largely limited to the collection and examination of fingerprints.* Modern crime laboratories are equipped with such highly sophisticated scientific instruments as photomicrographs, which can determine the kind of device a bullet was fired in, and computerized photograph enhancers, which, by increasing the picture resolution of an image, can reveal otherwise invisible details in photographs and video stills.* Crime scene evidence that was unusable a few decades ago, such as paint from the surface of a car, shreds of clothing and human hair or skin, can also be analyzed in modern police laboratories, providing additional clues and evidence.

Although “Bobbies” (so named after Peel) were not immediately popular and were often seen as a potential infringement on civil liberties, their work resulted in a sharp decline in crime rates and the overall structure and organization of the force became the example from which New York City created the first police department in the United States in 1844.
