According to Tombs, what is a significant factor in defining an act as crime?

Tombs highlights the significance of the power dynamics in society when it comes to defining what constitutes a crime. This perspective taps into the broader sociological understanding that crime is not merely an objective category based on harm or legality, but rather a social construct influenced by those in power. The ability of certain individuals or groups to shape laws and regulations underscores how legal definitions can reflect who holds societal power, allowing them to dictate what behaviors are criminalized.

In this context, the role of the powerful is paramount; they are often the ones who determine the legal frameworks that govern behavior. This observation can lead to a critical examination of bias in the law, where the interests of the powerful may be prioritized, potentially overshadowing issues of harm or morality linked to acts that are not classified as criminal.

The other options, while relevant in discussions about crime, do not capture the essence of Tombs' argument regarding the influence of power on legal definitions. Factors such as the severity of harm, location, or financial motivation might contribute to discussions about crime but do not encompass the structural impact of power plays in defining criminality as effectively as the recognition of who says what is considered a crime.
