...it can usually clarify the problem. In the skywalk example in Fang's article, without knowing for sure that the train *will* stop when it hit the fat guy, the rest of the problem will be moot. What if the fat guy will only slow the train by 20% and save 1 or 2 out of 5 people? Science will certainly help in clarifying the physics of this collision problem before any moral delima can be considered.
In Terri Schiavo's case, the dispute wasn't whether you should stop life support for people in PVS (although some people have been twisting the whole issue to their own agenda); it was about whether she should be diagnosed as such. In the end, overwhelming scientific evidence points to her not being able to recover. Most of the contrary evidence came from her family's wishful thinking, psychics and faith healers employed by her family, and a family doctor whose reputation amounts to a fraud. The court's decision was nothing if not scientific.
