Agencies that work for businesses and individuals with needs to secure their persons and premises or need investigative work are available in many locations. A set or a group of these can provide things like security guards in San Juan Capistrano. These are certain pros licensed to carry firearms for the purpose of securing any place that needs to be protected.
There are several classes of this place, like domestic, commercial, government installations and industrial. All have varied levels of risk or potential for danger, although these are all minimized or maximized with the presence of guards. But usually a good and reliable agency can minimize the danger posed to any establishment or person.
The protective personnel can be static or mobile, and they usually work with a number of other experts. Their agency itself will be working with the relevant agencies they need to work with to provide an unbreachable front to anyone with plans against any specific client. The base includes local police departments or sheriff offices.
The next tier involves state police and related agencies. And the third level includes federal organizations like the FBI, the Bureau of Alcohol Tobacco and Firearms, the DEA, transport security units and any relevant federal unit. Everything in the security works in total but is sometimes affected by priorities, politics and certain unique details on the ground.
The responsibility of guards is one unique detail, either connected to levels of security classifications or not. But usually there is a connection at least to the first level, because any firm worth its salt here needs to work with backup. For instance, if a group of men decide to rob a bank, alarms can call up the cops to assist bank guards.
The is something of a classic image of guards, a not too powerful line of defense against determined bandits. This, for their clients, is disabused from the start, because in actual fact the agencies that take on the jobs often have an intelligence network. Or they are working with all levels of intelligence details that is classified under economic and national security.
For private persons, they will prepare for the background details. For instance, enemies their client may have made in a career or in business or potential enemies which choose to target him at random. They will work to match up the client situation with any possible thing that may happen and brief the security personnel assigned to him or her.
Local police departments, state agencies and federal ones also provide licensing to any firm working in this sector. This provides further backup to any firm, which can mean the use of government resources to stop or if possible prevent any crime. Economics is a very important factor here, since any economic climate will be negatively affected by criminal events.
The guards themselves undergo training programs and exams that government programs run. They have a badge, are assigned necessary firearms, are provided complete communication needs and options for any given situation. They do no go into their job blind, but informed and prepared.
