“Do you have any idea how many bullets I pull out of corpses weekly? This isn’t just my lane,” Judy Melinek, a forensic pathologist, responded on Twitter. “It’s my fucking highway.”

Other medical professionals also challenged the NRA, sharing gruesome photos and anecdotes about what it’s like to be on the front line of gun violence. Four of them told BuzzFeed News on Monday via email that the toughest part of their jobs is speaking to the families of victims.

Robert Lyons, a cardiothoracic surgery fellow at the University of California, Los Angeles, told BuzzFeed News that “the raw emotion of that moment stays with every physician for the rest of their life.”
