What is the primary condition for licensed security officers to legally carry firearms while on duty?

The primary condition for licensed security officers to legally carry firearms while on duty is that their actions must align with specific state law. Each state has its own regulations governing the carrying of firearms by security personnel, including the requirements for licensing, training, and the situations in which a firearm may be carried. Compliance with these laws is crucial for ensuring that security officers operate within the legal framework established by their state, thereby minimizing liability and enhancing the safety of both the officers and the public.

While authorization from a supervising officer or having witnesses can be relevant in certain contexts or situations, these do not serve as the foundational legal requirement. Similarly, while local government authority may have some influence over security operations, the overarching and decisive factor remains adherence to the laws specific to each state regarding armed security personnel.
