There is nothing we can do to stop crimes from happening; crimes are inevitable. However, it is important to know how crimes originate, when they occur, where crimes are more likely to occur and who can commit such acts of violence. This knowledge gives law enforcement a better understanding on how to deal with these situations and to help make society a safer place. The imperfections of society contribute to the nature of violent crimes. Criminologists imply that violence can happen because of personal traits; something that is inherited, mental abnormalities, low intelligence, and dysfunctional relations. Ineffective families can also lead to violence for example the absence of a father figure can cause young children to react violently towards other children. Other forms of ineffective families are abusive parents, poor parenting, and rejection.
A death instinct which produces a desire for self-destruction, can urge a person to commit violent crimes as a natural instinct. In addition, the use of drugs and alcohol can trigger a person to react in a violent way without being fully conscious of their actions. The environmental surroundings of a person as well as the cultural customs can promote violent habits among individuals. The extent of violent crimes has no limit. Experts in criminology use information by different government agencies such as police departments. The FBI then takes this information from law enforcement agencies including crimes reported to authorities and number of arrests made by police agencies therefore, creating a huge data base known as The Uniform Crime Report.
