Narrative:

Cleared ILS 9L fll. Tower cleared us to land and issued TA of a helicopter over the expressway (by tower). TCASII followed with an advisory with traffic off right wing, coalt. TCASII RA followed at approximately 400 ft AGL. During discussion after landing which followed with tower chief, he felt that having this situation occur was justified due to the fact that the tower had both aircraft in sight! We at no time had the helicopter in sight.
