Attendees stand in line in a section that sells ammunition at the Rocky Mountain Gun Show in Sandy, Utah, U.S., on Saturday, Jan. 5, 2013. A working group led by Vice President Joe Biden is seriously considering measures that would require universal background checks for firearm buyers, track the movement and sale of weapons through a national database, strengthen mental health checks and stiffen penalties for carrying guns near schools or giving them to minors.
