According to the FBI Crime Clock, violent crime is committed somewhere in the country every 26.2 seconds. Law enforcement officers put their lives on the line every day to protect the lives and properties of law-abiding citizens.

The method they use to achieve this depends on the agency they work for and the jurisdiction that governs the extent of their work. From federal agents to county sheriffs, the presence of law enforcement in communities all over the country plays a huge role in maintaining law and order to allow people to go about their business without a care in the world.

This guide explores who’s who in law enforcement so that you can tip your hat to them the next time you see them.

Law Enforcement Background

Law enforcement in the United States has come a long way from what it was back in the very early days. At the time of the country’s founding, law enforcement consisted primarily of volunteer groups and community-funded part-time officers.

Today there are more than 18,000 federal, state, and local law enforcement agencies that employ over 420,000 officers. Their role is to uphold the rule of law and public safety so that no citizen’s liberty is trampled upon.

What Is the Definition of Law Enforcement?

Law enforcement, which is one of three arms of the American criminal justice system – the other two being courts and corrections – is the entity that ensures all members of the society comply with the set rules, regulations, laws, standards, and social norms. There are essentially three types of law enforcement agencies:

  • Local law enforcement, which includes the sheriff and police departments
  • State law enforcement, which includes state or highway patrols
  • Federal law enforcement, which includes federal agencies like the FBI and the Secret Service

Which Is the Largest Segment of Law Enforcement Today?

Which Branch of the Government Enforces Laws?

The federal government consists of three branches. There’s the executive which is headed by the President. Its role is to enforce laws. There’s the legislature known as Congress, which is the law-making arm of the government. Congress is made up of the Senate and the House of Representatives.

The third branch of the government is the Judiciary, which includes the United States Supreme Court and its nine Justices.

The criminal justice system, which comprises law enforcement, courts, and corrections, falls squarely under the executive branch.

Who Enforces What?

With that brief overview of what law enforcement is, it’s now time to break down what its different functions are. Here are the answers to some of the most frequently asked questions with regards to who enforces what.

Who Enforces International Law?

International law or “public international law” as it is commonly called, exists to regulate the activities and relations between different nations. It also details the rules governing the operations of international bodies like the United Nations (UN) and the state treatment of corporations, partnerships, associations, and individuals.

While local, state, and federal governments are charged with enforcing domestic laws, there isn’t any specific organization that enforces international law. The UN Security Council may pass certain policies authorizing enforcement. Still, their implementation poses a huge challenge since it requires member nations to provide resources – like military troops – to do this. This almost always never happens.
