How does the Fourth Amendment protect individual rights against governmental actions?
The Fourth Amendment protects individual rights by establishing clear guidelines that require law enforcement to obtain a warrant based on probable cause before conducting searches or seizures. This means that citizens have the right to privacy in their homes and personal effects unless there is sufficient reason for law enforcement to believe that criminal activity is occurring. This protection ensures that government actions are not arbitrary or invasive, thus upholding individual liberties.
