A violent crime is defined as:

A violent crime is characterized by offenses that involve the use of force or the threat of force directed towards an individual. This definition encompasses crimes such as murder, assault, robbery, and sexual assault, all of which result in direct physical harm or the immediate threat of harm to a person. The essence of a violent crime lies in its potential to inflict actual physical damage or to instill fear in individuals, making it distinct from non-violent offenses.

In contrast, the other choices describe different categories of crime. Financial loss is typically associated with property crimes or fraud rather than violent behavior. Crimes that involve drug trafficking may entail violence but do not fall under the violent crime definition per se, as the core of drug offenses often pertains to the distribution and possession of illegal substances. Lastly, non-violent theft crimes are explicitly devoid of force or threats, which further highlights the specific nature of violent crimes in regard to interpersonal aggression and danger. Thus, the definition aligns accurately with option B, emphasizing the role of force in these crimes.
