Compile a list of the top 25 guns/rifles used in murders and assualts.
Extend the waiting period and go beyond a criminal backround check. Figure out how many people who kill people with guns actually have a licence/own the gun they possessed at the time of the crime.
People who have children living in the home must either own a gun safe with combination or are not allowed to keep their weapon at their house.
Guns dont kill people, People who are not mature and are criminally inclined kill people. People who do not keep their weapons in a safe or in a child safe, or burglar safe place kill people. A gun is priceless because it can take somebodies life in the wrong hands. If a weapon that was stolen from you because of carelessness and bad habits in keeping it locked somewhere you should be liable for crimes that are commited with it up to a point.
