A proposed bill in the state Senate would require anyone buying a pistol or renewing their permit to be subjected to a review of their internet history and social media accounts going back up to three years.

David Hogg, a student who survived the Marjory Stoneman Douglas High School shooting in Parkland, Florida, is now a gun control advocate. He spoke with students Wednesday at Nassau Community College, saying social media background checks would save lives.

"The shooter at my school had indications on their social media beforehand," he says. "The FBI and local law enforcement was called over 38 times and they failed to do anything about it."

But some say social media checks won't be the answer to preventing mass shootings.

"The people who are committing these crimes have a psychological problem," says Andrew Chernoff, of Coliseum Gun Traders.

Gun rights activists also say the bill would violate multiple constitutional rights.

The bill currently is in committee and will have to clear several steps before it can become law, including being passed by the state Senate and Assembly.
