A young survivor of Uvalde's massacre, before the United States Congress.

Miah Cerrillo (11-year-old girl) implores Miah Cerrillo that she doesn't want it to happen again after the shooting at Robb Elementary School, Uvalde, Texas, on May 24, 2012. She described, Wednesday, June 8, before the United States Congress how she covered herself with the blood of a fellow student to escape the gunman's attention.

In the video below, you can see his powerful testimony at an American gun regulation hearing.

Salvador Ramos (18 years old) was a high school student who carried an assault rifle and killed 19 students and two teachers in this school west of San Antonio.

The shooter said "good night" to my teacher, and then he shot her in her head. He then shot some of my fellow comrades as well as the painting," an 11-year old testified during a Capitol hearing about the "epidemic" of gun violence.

The little girl in bespectacles said, "When I got near the backpacks, he shot my friend (who was right next me) and I thought that he was going back into the bedroom." Video.

"So I took some blood, and smeared it all on myself. I was quiet. Then I grabbed the phone of my teacher and dialed [the emergency number] 911."

Miah Cerrillo stated that she felt unsafe at school. She pleaded, "I don’t want this to happen again."

Miguel, Miah's father, was present at the audition and cried when he said that Miah wasn't the same little girl he used play with.

He pleaded, "Schools are not safe anymore. Something really must change."

The testimony of Roy Guerrero from Uvalde, a Uvalde pediatrician, has been presented to the United States Congress. He described children's bodies as "pulverized", decapitated, and "shredded" by bullets.

He blasted, "I don't get it, if our politicians let down because of stubbornness, passivity or both."

Zeneta Everhart (21-year-old boy who survived the racist attack at a Buffalo grocery last month) also challenged elected officials.

My son Zaire has a hole in his right side, three on his back and one on his leg. This was caused by an AR-15 [assault rifle] shot. She said that she could still feel the bullet fragments in her son's back while cleaning his wounds.

Joe Biden, the US President, has repeatedly pledged to take action against this terrible scourge that successive governments have been unable to stem. Conservatives strongly object to any measure that might violate the rights "law-abiding citizens" in a country where almost one third of Americans own at least one firearm.

A narrow majority of Joe Biden’s party in Congress doesn’t allow him to pass a gun legislation on his own. The challenge is to find ways to win support from Republicans.

The Senate is currently discussing limited proposals such as the verification, criminal or psychological, of individuals who purchased individual weapons. This has been requested by associations for many years.

Chuck Schumer, the Democratic leader of the House, stated Thursday that it would vote on "firearms controls measures" in the upper house, without providing further details.

The House of Representatives voted Wednesday night for another major bill, which would prohibit the sale of semiautomatic shotguns to anyone under 21 years old and high-capacity magazines.

The Republican opposition strongly criticizes these measures. They are therefore unlikely to pass the Senate stage, where ten conservatives must support them due to the rules of qualified majorit.
