"This February 4, 2013 photo illustration in Manassas, Virginia, shows a Remington 20-gauge semi-automatic shotgun, a Colt AR-15 semi-automatic rifle, a Colt .45 semi-auto handgun, a Walther PK380 semi-auto handgun and various ammunition clips with a copy of the US Constitution on top of the American flag. US President Barack Obama Monday heaped pressure on Congress for action ""soon"" on curbing gun violence. Obama made a pragmatic case for legislation on the contentious issue, arguing that just because political leaders could not save every life, they should at least try to save some victims of rampant gun crime."
