Congress enacts the Good Guy with a Gun Act. It provides up to $1,000 that specially qualified individuals can use to help purchase automatic rifles. Persons lawfully purchasing these arms can then use them to protect "Soft Target" areas such as schools, houses of worship, shopping malls and movie theaters that might be targets of terrorism or mass shootings.

Here are some additional facts.

• An automatic rifle is a firearm that does not require multiple presses of the trigger to discharge multiple rounds. Rather, the user just holds the trigger down and many rounds discharge. It is traditionally used in the military and somewhat difficult to lawfully obtain at present.
• No persons with felony convictions are eligible for the subsidy under the new law.

Which of the following is most accurate?

a) there is no obvious constitutional problem with the law; if it is a bad law, that is a matter for the political process to address

b) the law is unconstitutional because it does contain a requirement that the firearm have traveled in interstate commerce and does not contain findings showing a substantial effect on interstate commerce

c) the law is constitutional because crime has a substantial effect on interstate commerce

d) the constitutionality of the law could be strongly challenged under the equal protection clause (rational basis scrutiny) by an individual who might want to purchase such a weapon but, due to a felony drug conviction 20 years ago, is barred from doing so

e) the law is unconstitutional because military-grade automatic weapons like this are not traditional firearms used in self defense
