Medical professionals around the country are fighting back against the National Rifle Association (NRA) by sharing devastatingly bloody photos illustrating the aftermath of a shooting.

Last week, the gun rights group tweeted medical professionals should “stay in their lane” and linked to a blog post that criticizes the American College of Physicians for a paper written on gun violence prevention.

Once the NRA’s tweet went viral, some doctors and nurses challenged the NRA with medical research about gun violence. However, many others felt an image would make their case stronger than any statistic.

Now many medical professionals are sharing photos of them covered in blood after operating or treating shooting victims.

Adam Shiroff, the director of the Penn Center for Chest Trauma in Philadelphia, told BuzzFeed News he has treated shooting victims for more than 10 years.

"Without question, the most difficult part, as has been echoed recently by friends and colleagues on Twitter, is not the technical aspects of complicated and high-risk operations, it's the human aspect," he said. "It's having to change your bloody scrubs before you go talk to the family to tell them that their son is dead."

"It's standing at the sink after someone didn't make it to wash your hands six times to get the blood off because there was no time to change the glove with a hole in it. The realization that it could have been your son, daughter, father, mother who was shot because bullets don't care if you are black or white or rich or poor."

"It's devastating to the health care team and we do it every single day."

"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 f—ing highway."
