Stalking generally refers to a course of conduct, not a single act. Stalking behavior includes following a person, conducting surveillance of the person, appearing at the person's home, work or school, making unwanted phone calls, sending unwanted emails, unwanted messages via social media, or text messages, leaving objects for the person, vandalizing the person's property, or injuring a pet. Stalking is a serious crime. Victims experience fear for their safety, fear for the safety of others and suffer emotional distress. Many victims alter their daily routines to avoid the persons who are stalking them. Some victims are in such fear that they relocate to another city, town or state. While estimates suggest that 70% of victims know the individuals stalking them, only 30% of victims have dated or been in intimate relationships with their stalkers. All stalking victims should be able to seek a civil remedy requiring the offenders stay away from the victims and third parties.
