What is the difference between the 14th amendment and the 5th amendment?

The Fourth Amendment protects your privacy from say FBI surveillance, unlawful arrests, and many other things like that. You can find more information here: https://www.law.cornell.edu/constitution/fourth_amendment

The Fifth Amendment basically protects your right of speech if I am not mistaken. You could be in a courtroom, and a lawyer could ask you a question but you wouldn't necessarily have to answer because of your right to exercise the Fifth Amendment.

Let me know if this helps. :D
