Final answer:
d) law enforcement arrests people who sell alcohol to minors.
For a policy about underage drinking to be effective, it is essential that law enforcement takes action against those who violate the policy, such as selling alcohol to minors. This direct enforcement is more crucial than public votes or legislative review for immediate compliance and safety.
Step-by-step explanation:
The effectiveness of a new policy about underage drinking, such as the National Minimum Drinking Age Act of 1984, largely depends on enforcement rather than solely on public vote or legislative review. While informed voting and legislative transparency are vital democratic processes, for a policy to be effective, especially one concerning public safety and underage drinking, stringent enforcement actions are imperative.
Therefore, law enforcement arresting individuals who sell alcohol to minors is a critical component for such a policy to be effective, as it directly addresses the behavior that the policy aims to curb.
Engagement between lawmakers, law enforcement, and the public is essential for the culturally sensitive and practical implementation of these laws. The history of alcohol regulation in the United States, influenced by organizations like MADD, underlines the ongoing debate about the most effective age regulations for alcohol consumption and the impact of these laws on youth behavior and public safety.
