OMG! Yet another brilliant illustration of how broken is the US legal system. There are a couple of side issues. How on earth can Navy corpsmen come out with different qualifications from anyone who has been through the same gauntlet of fire in the Army or Air Force? Then, how can these legal systems not work together? With different states having different laws (another problem!) there are understandable areas of friction, but if some law enforcement body is pursuing someone through their investigation a village cop should not be able to block that investigation, and vice versa. But the principal question is: Why should someone coming on someone else in distress not be permitted to help them, let alone be prosecuted for doing so? There are references in other reviews to "Good Samaritan" legislation. Why on earth should such be necessary? People must respond to the need of others! If while hill-walking I come across someone with a broken leg and help them by splinting it so that it is less likely to set badly, am I criminally liable? As another reviewer has suggested, if a mother puts a plaster on her child's knee, is she in danger of prosecution? What sort of legal system even thinks of such idiocies?
EDIT 2/4/23:
On the fourth (?) time of viewing, I find that this episode is perhaps the one that makes me most angry out of the whole series. I accept that when the US constitution was written in 1789, Franklin and the other authors were anxious to ensure the rights of individual states against the proposed federal government, but I have two serious issues here. One issue is how someone who is employed by the federal government to carry out a task (battlefield medic) should not have the recognition of that training and experience in all states. The other issue (and perhaps more worrying) is that anyone might be considered to have committed a crime because they tried to help someone in distress. No matter what our level of training may be, no matter our qualifications, we are called as Human Beings to succour any other being (human or otherwise) that needs our help. If we see children in a burning building, and the Fire Brigade is not there as professional rescuers, we may rush in to try to save the children. Under what legal system could that be a criminal act? "Good Samaritan" laws are redundant: we all have to do what is necessary to help other beings. Standing by and not using whatever skills or abilities we might have would be an actual crime. I move my rating up to 10 because the episode makes the point so well.
