An officer checks everyone's ID and arrests all who are underage among a group of teenagers drinking beer. This example typifies which officer style?

This scenario exemplifies the law enforcer style of policing. Officers who adopt this approach focus on maintaining order by strictly applying the laws and regulations. In this case, the officer is actively checking IDs and arresting those who are underage, which demonstrates a commitment to enforcing the law without discretion for the circumstances surrounding the behavior.

The law enforcer style is characterized by a primary focus on law and order, where officers prioritize the application of rules and legal standards in their actions. This contrasts with other styles, such as the social agent, who may emphasize the social aspects of law enforcement and aim to address community needs, or the watchman, who often takes a more passive approach, focusing on maintaining general order without strictly enforcing the law in every instance. The crime fighter style is associated with a more aggressive approach to tackling serious crime, rather than routine enforcement of laws in everyday situations like underage drinking.

Thus, in this case, the officer's actions clearly align with the law enforcer style, as they are primarily focused on the legal implications of the teenagers’ actions.
