The AC360 Weekly Buzz: Same-sex marriage, SCOTUS, gun control, Mandela, Amanda Knox, urinal video games

What everyone’s talking about:

The U.S. Supreme Court heard arguments about the legality of California’s Proposition 8 and the Defense of Marriage Act this week. CNN’s Jeffrey Toobin and Gloria Borger gave all the details of what happened inside the courtroom. Anderson spoke to civil rights activist Julian Bond who compares the fight for gay rights to the civil rights movement. He says “these are the same issues, the same struggle.” HLN’s Dr. Drew Pinsky addresses the argument that same-sex couples have a negative effect on children. He says studies show there's no harm done. Anderson also spoke with NFL punter Chris Kluwe of the Minnesota Vikings, who has been outspoken about marriage equality. Kluwe believes everyone should have the right to marry the person they love, just as he was able to do with his wife.

On Thursday President Obama urged Americans to pressure their elected leaders to pass stricter gun laws. 100 days after the Newtown school massacre, family members of the victims were present at the president's press conference to show their support. “We need everybody to remember how we felt 100 days ago and make sure what we said wasn’t just a bunch of platitudes, that we meant it,” he said. Anderson spoke with Democratic Strategist Cornell Belcher and The Washington Times’ Emily Miller about the politics of gun control and the president's efforts.

Former South African President Nelson Mandela is making “steady progress” after being rushed to the hospital for a lung infection this week. CNN’s Robin Curnow reports on his health.

Today’s Scoop: 

Italy’s highest criminal court overturned Amanda Knox and Raffaele Sollecito's acquittal in the 2007 killing of Knox's roommate, Meredith Kercher. The couple was convicted in 2009, but the verdict was overturned by a jury in 2011. Now, after four years in an Italian prison and an attempt to start her life over in the U.S., Knox is on trial again. The salacious circumstances of the case and disturbing evidence are back in the spotlight. Watch tonight’s Anderson Cooper Special Report “Murder Abroad: The Amanda Knox Story” at 8 and 10 p.m. ET.

Looking ahead: 

Former Tucson, Arizona, mayoral candidate Shaun McClusky is introducing a privately-funded program to provide free shotguns to residents in an area of Tucson with high crime rates. The program is modeled after an initiative launched in Houston with the goal of arming citizens nationwide. CNN’s Miguel Marquez has the story next week.
