Having a job in Law Enforcement can span across the board. There are so many different positions in the city, state, and federal Law Enforcement jobs, that this is a difficult answer to give. I do write a blog that covers a lot of information regarding the many positions and what each of them do.
I would check with texas police or the US marshalls to see if there are positions available with Border Patrol. You probably have to have pass a law enforcement test first.
The only law enforcement officers available on the American frontier were the U.S. Marshals and local sheriffs or deputies.
Their are many jobs available in the US government. Some of them are security and protection, legal, medical and public health, program management, and enforcement and compliance.
(in the US) that would be your local law enforcement agency. All law enforcement agencies in the US are tied with a nationwide computer system and they ALL draw upon the same database, which is NOT available to, or accessible by, the general public.
YesAdded: U.S. Marshalls ARE law enforcement officers and have jurisdiction ANYWHERE in the US, its territories and possessions.
(in the US) virtually every law enforcement agency has a manual of procedures and rules that govern the actions of their officers when enforcing the laws of their particualr jurisdiction. These manuals should be available as "public documents" or you can access them with an FOIA request.
The same way any law enforcement agency deals with crime: Find them, arrest them (and/or deadly force), try them in a court of law, administer justice (death, imprisonment, etc.). There are MORE different types of Law Enforcement Agencies in the US alone than there ever was in US history before. Today's law enforcement agencies have COMPUTERS, WEAPONS, and OVER-SEAS JURISDICTIONS. Today's law enforcement agencies also have the US MILITARY to assist them in law enforcement; this is "New", law enforcement did not have "official" military assistance prior to the 1990's.
In the US, there is no Federal requirement or procedure for registration of firearms. A few states require registration. That information is not available to the public, but may be available to law enforcement.
The police and law enforcement protects us from thieves and can arrest them

(in the US) Law enforcement agencies are not even a part of the court system. Law enforcement agencies are part of the EXECUTIVE BRANCH of the government. The court system is part of the JUDICIAL BRANCH of government.
