Differences between the Constitution and constitutional law

This assignment asks you to look at the differences between the Constitution and constitutional law, by looking at two Supreme Court Cases.

Look at the text of the Fourth Amendment. Does the amendment define exactly what an Unreasonable searchis? How did the Supreme Court interpret the meaning of Searchin the case Katz v. United States, 389 U.S. 347 (1967), and how did it differ from its interpretation in Olmstead v. United States, 277 U.S. 438 (1928), which the Court overruled? Is physical intrusion necessary to fall within the meaning of a Search”? Why or why not, according to Katz? Be sure to delineate at least four differences between the Fourth Amendment and its interpretation.
