Leading questions—questions worded in such a way as to suggest a particular answer—can yield unreliable testimony either by design, as when a lawyer tries to trick a witness into affirming a particular version of the evidence of a case, or by accident, when a questioner unintentionally prejudices the witness’s response.

Leading questions
Framework
Problem / Solution, or Old / New
The passage is primarily about the Problem of leading questions, but there isn't a Solution discussed.
And the passage is primarily about our New, better understanding of the danger of leading questions, but there's not much time spent on our Old mindset of knowing-less about leading questions / not seeing them as problematic.
Main Point
NEW/PROBLEM Recent studies are making us more aware of some problematic aspects of leading questions and of the underlying conditions that give rise to these problems.
Summary
P1 - Intro to Topic, Pivot into Problem
The author introduces us to leading questions and establishes that while leading question re a known problem in the courtroom (which is why judges may disallow them), they are a less-appreciated problem outside the courtroom. The "But" in the middle of this paragraph is one of those classic Author Pivot moments that pulls into focus the foreground of what we'll be discussing.
P2 - New research findings on leading questions
This paragraph presents our emerging understanding from new research, about how leading questions asked pre-courtroom could still bias witness testimony. Our memories have fuzzy details and incomplete details, and new information contained in a leading question that doesn't conflict with our memory will basically be absorbed into our memory. An example is provided in which an eyewitness comes to have a belief about a stop sign via a leading question.
The first sentence of this paragraph has the famous Author Pivot word of "Recent", and this sentence ultimately seems like our closest thing to a Main Point sentence.
P3 - Further implications of New research
This paragraph just continues to flesh out the research findings. It emphasizes that those fuzzy details are usually things that are distant in time and weren't super germane to the original memory. Since we're most likely to be misled by leading questions when it comes to tangential details like someone's shoes, or car, or hair, etc. the fact that many eyewitnesses are relied upon to give identifying testimony regarding small details like that highlights the danger of how leading questions could have important ramifications.
