'No one should be able to inflict these types of injuries'
At the March For Our Lives rally in Los Angeles, one woman held a sign reading: "Send the guns to Ukraine."
Dr. Jeffrey Birnbaum, a pediatric emergency medicine doctor in LA and a Parkland, Florida, native, explained the severity of semi-automatic rifle injuries.
He recalled his first experience treating patients shot by semi-automatic rifles, saying "the images of their injuries will be forever burned into my mind."
"I vividly remember thinking that no one should be able to inflict these types of injuries on a fellow human being," Birnbaum told the crowd.
A survivor of the 2014 mass shooting at the University of California Santa Barbara also shared her experience at the LA rally. She said after the shooting, her mother begged her to drop out of college, terrified for her safety.
Last month's Uvalde, Texas, shooting came one day after the anniversary of the UCSB massacre. She said she doesn't want any other generation to endure this grief.
"I know that we are exhausted -- but we must continue showing up … because I can't take it anymore," she said.
