David Chipman, a retired Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) agent, said on Monday that a public health approach should be taken to prevent mass shootings.

“A lot of gun laws are sort of like a flu shot. What we’re seeing in these mass shootings is determined killers being transformed into killing machines because of the lethality of the weapon," Chipman told Hill.TV's Buck Sexton and Krystal Ball on "Rising." Chipman is now a senior policy adviser at Giffords: Courage to Fight Gun Violence, the group formed by former Rep. Gabby Giffords (D-Ariz.), who survived an assassination attempt in 2011.

“If we took a public health approach, you know, perhaps we can’t prevent one or two people from getting killed, but perhaps we can keep hundreds [from] being wounded, like in Las Vegas, where today bump stocks are still legal," he continued.

“We have victims who survived Las Vegas who now have died, and we still haven’t dealt with that one thing that could prevent the next mass shooting," he said, referring to Telemachus Orfanos, who survived last year's Las Vegas strip shooting at a country music festival, but was killed in last week's mass shooting in Thousand Oaks, Calif.

The debate over gun control has been reignited in recent weeks after multiple people were killed in mass shootings in a mass shooting at the Tree of Life Synagogue in Pittsburgh and the Borderline Bar & Grill in Thousand Oaks.

Congressional Democrats have vowed to move quickly on strengthening federal gun laws next year.
