The Occupations Code provides the statutory authority for ___________ to establish rules that law enforcement agencies and corrections officers must follow.

The correct answer is TCOLE, which stands for the Texas Commission on Law Enforcement. This organization is responsible for setting and enforcing standards for law enforcement agencies and corrections officers in Texas. TCOLE's authority derives from the Occupations Code, which empowers it to develop and implement regulations that ensure the professionalism and accountability of law enforcement personnel.

The rules established by TCOLE cover various aspects of law enforcement practices, including training requirements, licensing, and ethical conduct. By having a dedicated regulatory body like TCOLE, the state ensures that all law enforcement and corrections officers adhere to consistent standards, promoting public safety and trust in these institutions.

In contrast, the FBI operates at the federal level and typically focuses on national law enforcement issues rather than state-specific regulations. The ACLU is an organization that advocates for civil liberties and may challenge law enforcement practices but does not have the authority to establish legal rules or standards. The DEA, or Drug Enforcement Administration, focuses on drug-related law enforcement at the federal level and does not oversee corrections officers' training or practices.
