If someone is back day after day, he or she is probably on the payroll. Sometimes it's a lawyer, sometimes a professor, sometimes a retired general. They are usually more glib, more opinionated, and more forceful than the nonpaid guests. They are also more to be doubted. Just because information comes from a computer doesn't make it true.
Many people think a printout guarantees accuracy and truth.
A computer is a gossip and a liar if the person who put the data in it is a gossip and a liar. Computers are machines, not filterers weeding out chaff or editors seeking out truth. Computers make no distinction between fact and fiction. They are filled with useful information that helps you lead your life and lets you check out claims made by politicians and others. Learn whom you can trust and whom you can't.
