Pew Research Center for the People & the Press. July 30, 2012.
There has been no significant change in public views on the issue of gun control and gun rights following the July 20th shooting at a movie theater in Aurora, Colorado. Currently, 47% say it is more important to control gun ownership, while 46% say it is more important to protect the rights of Americans to own guns. That is virtually unchanged from a survey earlier this year in April, when 45% prioritized gun control and 49% gun rights. [Note: contains copyrighted material].

Congress has debated the efficacy and constitutionality of federal regulation of firearms and ammunition, with strong advocates arguing for and against greater gun control. Since March 2011, much of the gun control debate in the 112th Congress has swirled around allegations that the Department of Justice (DOJ) and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) mishandled a Phoenix, AZ-based gun trafficking investigation known as “Operation Fast and Furious.” In the Consolidated and Further Continuing Appropriations Act, 2012 (P.L. 112-55), Congress included a provision that reflects a Senate-adopted amendment that forbids the expenditure of any funding provided under it to be used by a federal law enforcement officer to transfer an operable firearm to a person known or suspected to be connected with a drug cartel without that firearm being continuously monitored or controlled. The act, however, does not include language adopted during House full committee markup to prohibit ATF from collecting multiple rifle sales reports in Southwest border states.
