Law Enforcement

"Above all, I would teach him to tell the truth. Truth-telling, I have found, is the key to responsible citizenship. The thousands of criminals I have seen in 40 years of law enforcement have had one thing in common: Every single one was a liar."

- J. Edgar Hoover


Enforcement Agencies

Law encompasses virtually every aspect of modern life. For good reason, law enforcement agencies are many and varied. Although many may appear similar, each has a different mission. And each bureaucracy has an enforcement arm.


Enforcement History

The history of Modern Law Enforcement can be traced to organizations like the Boston Watch, the London Metropolitan Police, the Texas Rangers and many others. Examine now, all contributions to modern policing worldwide.

Enforcement Careers

Law enforcement careers are often the preferred direction for those seeking degrees in Criminal Justice. However, not all careers are as glamorous as the movies would have us believe. Career paths vary by goals and training.



Enforcement Tech

Technology has always had an impact on law enforcement. From fingerprint tech to the automobile to the mobile radio then DNA and now the Internet, technology often brings monumental changes to policing.




Forensics is a separate, integrated branch of law enforcement. While Hollywood has romanticized the field, forensics is really a field for those with a taste for long hours in a lab coat analyzing evicence samples.

While the Federal Department of Justice holds ultimate authority over all law enforcement efforts in the United States, the jurisdictions are divided among four general levels of governance. These are Federal, State, County and Local.

And it should be noted that global law enforcement efforts largely follow these or similar distinctions. Nearly every nation allows smaller jurisdictions a degree of lattitude in policing their populations. For this reason, the oversight sections will examine the U.S. model, but also provide insights into differences worldwide.

Federal oversight of law enforcement in the U.S. is through the Department of Justice. The FBI is perhaps the most visible, but not the only agency under the DOJ.


la state trooper badge

While Troopers are the most visible of state law enforcement, each state has multiple agencies which serve specialized functions.


la county sheriff badge

Each county in the U.S. has some form of law enforcement, the most visible being the Sheriff's Department.



On a local level, cities, towns and villages have local law enforcement agencies, most often referred to as Police Departments.
