Question

What is the main idea of Katz v. the United States? Why is that idea important to the DLK case?

Answer 1

@smokeybrown would you be able to help with this?

Answer 2

I'm not very familiar with either case, but I did a quick online search, and I think I understand the basic idea.

Katz v. the United States involves the question of what should be considered a "search and seizure" for gathering evidence. Keep in mind that the 4th Amendment of the US constitution protects against "unreasonable searches and seizures"
In the Katz case, the conflict involved the FBI listening in on Katz phone call through a hidden listening device placed at a public phone booth. Based on my understanding, it seems that the court ruled that even though the call was made at a public phone booth, it could be understood that Katz had a presumption of privacy in that context, so the information gathered in that way counted as a "search and seizure" which Katz should have been protected against

Similarly, the DLK case involved thermal imaging evidence taken from outside of a person's private house. Although the house itself was never searched, there is a question of whether or not this kind of evidence breaches privacy and should be counted as a "search or seizure".

More broadly, the cases call into question how far the protection of the Fourth Amendment can possibly extend if, in the future, more advanced technology makes it easier and easier for our privacy to be breached. Off the top of my head, social media comes to mind as one possibility, and there are probably other scenarios where this question could be relevant to our lives
