10. Does the Second Amendment guarantee a personal right to own fully automatic military-issued combat rifles, heavy machine guns, and perhaps even shoulder-fired missiles?
You answered:
Yes.
Correct answer:
Probably not.
The majority justices in the 2008 Heller decision said the Second Amendment protects the right of Americans to possess firearms in common use – meaning rifles and handguns commonly used by civilians. The issue may be litigated in a future case, but Justice Antonin Scalia, writing in the Heller decision, suggested that the states and Congress would not violate the Second Amendment by passing and enforcing restrictions on machine guns and specialized military weapons.
At least they said "Probably not", which correlates correctly with the SCOTUS decisions but still not the correct answer. The Second Amendment, per US vs Miller, protects fully automatic military-issued combat rifles, heavy machine guns, and perhaps even shoulder-fired missiles significantly more than engraved duck guns.
11. Does the Second Amendment guarantee a personal right to own semi-automatic rifles that resemble the fully-automatic military versions of the same firearm?
You answered:
Yes.
Correct answer:
Not clear at this point.
This is one of the thorniest unresolved questions in the wake of the Heller decision. In overturning the District of Columbia’s ban on handguns in 2008, the high court said handguns – including semi-automatic handguns – are constitutionally protected because they are in common use by law-abiding citizens. The question now is whether a majority of justices will find that semi-automatic rifles – which are also in common use by law-abiding civilians – enjoy the same constitutional protection.
Again, technically true if referring solely to recent SCOTUS decisions. Semi-automatic copies of full auto military weapons could be argued that they are necessary training or economical alternatives to actual service rifles. Or near identical functionality.
I cannot say the quiz is wrong, per se. Only that it relies on interpretation of recent SCOTUS decisions.
