Private Jones

Private Jones is a Mr Gutsy robot who can be found in rivet city in the bridge tower. If you talk to him he will tell you that the area you are in is off limits. If you have a high enough speech skill you can convince him that there are enemy forces on the ships deck and he will thank you for the 'assist' before hurrying off. Roughly thirty seconds later he will resume his post and will not try to kill/arrest because you lied to him.

NOTE: this will not lose you karma.
