Nowadays in the US the government does a good job of keeping its citizens more-or-less safe, and so most people don't put any thought into their personal security. They just let the government deal with it.
However, there are still some situations in which the government does not have the same level of control, and often it seems that people don't adapt and try to protect themselves.
People may go into dangerous neighborhoods without the appropriate amount of caution.
People may wear expensive clothing that marks them as a target for muggings without taking appropriate cautionary measures.
A man who ends up with a woman (eg walking down a street) may not change his behavior to be more cautious when in fact he should.
On December 14, 1955, Darrel Parker came home for lunch from his job as a forester in Lincoln, Nebraska. A recent graduate of Iowa State, he had moved to Lincoln with his wife, Nancy, who worked as a dietician for a flour-and-noodle company and had a cooking show on the local television station. He found her dead in their bedroom. Her face was battered, her hands and feet were bound, and a cord had been knotted around her neck. The medical examiner later determined that she had been raped before the murder.
How do you make sure this does not happen to your family?
