Answer:
The Second Amendment is considered controversial because everyone can own and use guns.
Step-by-step explanation:
The Second Amendment to the Constitution of the United States of America protects the right of the American people to possess and bear arms. Thus, the United States is one of the countries with the least limitations in acquiring and carrying firearms.
The Supreme Court of the United States has clarified in numerous occasions the constitutional text: it has affirmed that the right to bear arms is an individual right that all Americans have, but also it has declared that the right is not unlimited and that it does not prohibit the regulation of the production and purchase of firearms or similar devices. The Second Amendment establishes that neither the federal government of the United States nor the state and local governments can infringe the right to bear arms.
