Answer:
3. The Supreme Court redefined what constitutes a handgun under the Second Amendment
Step-by-step explanation:
When the Supreme Court enforced the decision in all states that individuals have the right to own a firearm at home for self-defense, the Supreme Court redefined what constitutes a weapon under the Second Amendment.
This is because it is the second amendment that establishes the citizen's directory and duty to provide their own security through firearms. In other words, according to any citizen amendment, regardless of gender or color, being of legal age and being psychologically healthy, you can have a firearm that guarantees your personal safety whenever necessary.
