You are conflating two different things. The law is what it is. It defines what is legal and what is not. What happens at trial is not just about law. The points you raise touch on the other factors that are involved. What the evidence is, the skill of the lawyers presenting that evidence, and the attitude of the jurors hearing that evidence all matter too. But those things are not the law. They impact the final outcome of the trial, but should not be conflated with what the law is.
