Understanding Amendments 2 and 4
Amendment 2 talks about the right to keep and bear arms, it shall not be violated as citizens of the US. Amendment 2 affects us today because it acknowledges the right to own and carry a firearm for hunting, target shooting, and personal protection against criminals.
Amendment 4 is all about the people being secure with their persons, houses, papers, etc. Unreasonable searches are not allowed unless a police is told to search. Amendment 4 affects us today because without it, people wouldn't have any privacy and the police would have the right to search and take anything they want at any time without being told to.
