I’m working on a criminal justice multi-part question and need an explanation and answer to help me learn.

Assignment 7A
The Prompt: For this assignment, examine how changes in society (or society’s values) can cause changes within the legal system. Select a modern-day topic (one within the last 5 years) that you believe meets this criteria and explain why or how this change in societal thinking changed the legal system. How well has the change been accepted by the general public and what are the perceived or actual ramifications of this change?
The Requirements: This assignment should be at least 350 words in length 
Discussion Question on Chapter 20 Material
Throughout the semester, we will have various sets of discussion questions that relate to the material that we are covering. For these assignments, I am really just looking for you to offer a developed opinion after you interacted a bit with the chapter material. As always, I will provide you with feedback explaining your grade when commenting on your post to you directly. Responses to all questions this semester should be a least a few sentences long to be considered fully developed–some might be longer depending on the question. 
Please provide a response to the following questions:
(1) Out of all of the research studies that were discussed in this chapter:
Stanford Prison Experiment
Tearoom Trade
Obedience to Authority
The Kansas City Preventive Patrol Experiment
Minneapolis Domestic Violence Experiment
which do you think had the most serious ethical concerns? Why do you feel this way? 
Assignment 8A
The Prompt: For this assignment you will need read the article entitled “The Practice of Law As A Confidence Game” by Abraham Blumberg. After reading the article I want you to relate the title to the article; in other words, how is the practice of law a confidence game? How is this con game carried out and for what purpose? Be sure to use quotes from the article to support your argument.
