Both federal and state law fugitives, violent & non-violent, are returned to their "home" jurisdiction by both federal and state law enforcement and those agents & officers are armed as they ordinarily would be.

There are hundreds of these transports every day. I am very surprised that OP, if he is a regular flier, has not routinely encountered this situation on UA and other carriers. Ordinarily the prisoner & escorts would have been pre-boarded, most often from the ramp. But, there is no requirement and certainly no particular issue in the way this was handled.
