Can department of veterans affairs police officers carry off duty?

Legally and lawfully - if they are considered to be sworn law enforcement officers by the state, they may legally carry a firearm. HOWEVER - their agency (Dept. of Veterans Affairs) may have some kind of an agency policy or rule that states that they may not.

Under H.R. 218, VA police officers are given lawful authority to carry off-duty. This is a mandate by Congress which allows ALL federal law enforcement to carry off-duty. Though a VA facility may prohibit the bringing of off-duty firearms to work, the facility cannot overturn the Congress in terms of H.R 218.
