First, emphasize that there is no evidence whatsoever that these measures work.
What happens to Fourth Amendment, protecting against unwarranted searches,
Second, while you are correct on the implications to the rest of the bill of rights, I think you want to limit the discussion on the first amendment, since people rationalize that "words don't kill."
Zero in on the Fourth fifth, sixth and eighth amendments. They make it harder to convict criminals and let them out on the street. but like the second amendment the fourth, fifth, sixth and eighth give us absolutely necessary protections and LOTS of crime and harm can be associated with the fact that those exist.
Ask the question: do we want a future president to surround themselves with children and explain how they are harmed by the fourth, fifth, sixth and eighth amendments in order to reduce those rights?
