If he works there and thinks it is OK, I would say 'go for it'. He bought it and if he has it delivered somewhere where confiscation may be an issue.... it is his problem, not yours.
The Texas AG offices are not a 'metal detector- guard with a wand' type high security facillity, likely Florida isn't much different. What I remember they seem kinda like any ol' office. If it is located inside a federal building or a courthouse HE could get in trouble.
Let him have it.
