State Sen. Linda Lopez, D-Tucson, is proposing three changes to state law that she says will "keep guns out of the hands of dangerous individuals."

Her proposal focuses on three areas:

Background checks: Lopez wants to change the law to require background checks for all gun purchases. The change would add background checks for those conducting private sales and sales at gun shows.

Police gun sales: The proposal would repeal a law that requires police and other law enforcement agencies to sell guns they seize from crime scenes. Lopez says the guns should instead be destroyed.

Ammunition clips: Lopez proposes banning the "sale, possession or transfer" of magazines or clips that hold more than 10 rounds of ammunition.

Lopez announced her proposal today, but the legislation must go through the state Senate, House and get Gov. Jan Brewer's signature before becoming state law.

While Lopez' proposal is in response to the Sandy Hook Elementary School shooting, among others, she says it is aimed at generally preventing gun violence here. Other elected officials have made proposals specifically related to school safety, including arming school officials and adding security to school buildings.
