Federal law provides a number of important tools that are available to combat cyberstalking. Under 18 U.S.C. 875(c), it is a federal crime, punishable by up to five years in prison and a fine of up to $250,000, to transmit any communication in interstate or foreign commerce containing a threat to injure the person of another.
Section 875(c) applies to any communication actually transmitted in interstate or foreign commerce - thus it includes threats transmitted in interstate or foreign commerce via the telephone, e-mail, beepers, or the Internet.
