Christian Security Institute

The Christian Security Institute™ (CSI) is licensed by the Texas Department of Public Safety – Private Security Bureau – License #F01109. CSI is a Texas state licensed training company that trains security officers.
Each state in the U.S. has different security laws and regulations. What is legal in some states is illegal in others. In some states you only need a concealed carry license (or no license or permit at all) while other states deem it necessary to document that a person acting in a security officer’s role be adequately trained in the various skills necessary to fulfill that role. Most people would agree that you need to know more than how to shoot a gun in order to fill that role.
Your security team training should include the state laws regarding breach of the peace and deadly force, de-escalation, non-lethal hand-to-hand defense techniques, intermediate weapons (pepper spray, Taser or expandable baton) and deadly force (handgun, shotgun, rifle). A program based solely on handguns is totally inadequate and at best very litigious. You may be held liable for failure to train, etc. You need to know whether your state requires a “Security” license in order to provide security services.
This is NOT the same as a Concealed carry permit/license.
This is NOT whether it is legal to “Have a Gun in a Church”!
These are sometimes complex issues involving research into state laws and regulations. You will need to contact the state authorities that license security services, if any.
