Choose the correct statements regarding gun control policies from the list below (choose all correct answers).

A. Stand your ground laws, or "castle doctrines," expand the legal justification for the use of lethal force in self defense. These laws lead to a decrease in burglaries and robberies, but no change in murders and nonnegligant manslaughters.

B. When states increase purchase delays (the time between purchase and delivery of a gun), firearm suicides decrease with no increase in suicides by other means.

C. When states expand their gun background checks to examine issues like restraining orders, firearm homicides decrease.

D. When states expand background checks to examine mental illness, firearm suicide decrease.

E. Australia's gun buyback program led to a large decrease in both firearm homicides and firearm suicides.

F. Deer hunting season is related to an extremely large increase in the number of guns. This large increase in guns is bad news, both for deer, and for violent crime levels, which increase during gun season.

G. Gun shows lead to an immediate and sustained increase in both homicides and suicides, which is attenuated in states which have eliminated the "gun show loophole."

H. Right-to-carry laws were initially thought to decrease crime, due to an influential paper by John Lott and David Mustard, but that paper's results have been overturned by newer research.
