Fraud is the deliberate misrepresentation or falsification of facts or articles with the aim of cheating, and can involve products, services, or practices. There are many different types of fraud, and many different laws and agencies to conduct fraud investigation or aid in its prevention. Federal and state laws protect the consumer from dishonest manufacturers and those who sell their products or services. If a defrauder uses the Internet or the U.S. Postal Service with the intention of defrauding you, they may be punishable under federal law. Identity theft, which is the criminal and unauthorized use of another person's identity with the intent to defraud, is also a federal crime. The General Accounting Office is the federal government's agency for examining all matters related to the use of public funds, including such matters as embezzlement and misappropriation of funds. In most cases, currency fraud or forgery comes under the jurisdiction of the Treasury Department and the U.S. Marshall's Office, while frauds involving securities are generally handled by the Securities Exchange Commission, or SEC (S-E-C). If you believe you're the victim of fraud, you should file a complaint with the police.
