Stalking laws in most states pertain to a relatively new crime involving a clear pattern of conduct in which the offender follows, harasses, or threatens another person, putting that person in fear for his or her safety. An individual may be charged with stalking regardless of any pre-existing relationship with the victim. Stalking victims can range from celebrities to former spouses who have obtained a protective order against their ex.

For example, Dan spends a number of hours each week harassing Victoria, his former girlfriend, by following her home from work, sending her threatening emails, and calling her in the middle of the night.
