What protection is granted by the Fourth Amendment?

The Fourth Amendment to the United States Constitution is primarily concerned with protecting individuals from unreasonable searches and seizures. It establishes the principle that law enforcement must have probable cause and, in most cases, a warrant issued by a judge to conduct searches of private property or to make arrests. This protection is fundamental to ensuring citizens' privacy and personal security, reinforcing the idea that individuals have the right to be secure in their persons, houses, papers, and effects against arbitrary interference by the government.

In contrast, the other choices reference different amendments or rights: the protection against double jeopardy is found in the Fifth Amendment, the right to a speedy trial comes from the Sixth Amendment, and the right to bear arms is included in the Second Amendment. Each of these serves distinct purposes within the Bill of Rights but does not pertain to the protections outlined in the Fourth Amendment.
