In a video released on Youtube, parents experimenting with a nightmare are seen begging police officers to try to capture the teenager gunman who opened fire at Robb Elementary school in Uvalde.
“It’s my daughter!” one woman bellows amid chaotic scenes of crying and shoving.
In another video, parents are seen complaining angrily that Texas police are doing nothing in the worst school shooting in a decade in the US.
One woman, frantic about her son, yells to the police, “if they’ve got a shot, shoot him or something. Go on.”
Jacinto Cazares, whose daughter Jacklyn died on Tuesday, said he raced to the school when he heard about the shooting.
“There were at least 40 lawmen armed to the teeth but didn’t do a darn thing (until) it was far too late,” Cazares told ABC News Wednesday.
“The situation could’ve been over quick if they had better tactical training.”
The incident has led in recent days to criticize many US officials and lawmakers to neglect gun laws in the country.
Mexico on Thursday accused US gunmakers of “clear negligence” following the massacre of 19 children and two teachers at an elementary school in Texas.
“There’s clear negligence on the part of this industry,” Mexican Foreign Minister Marcelo Ebrard told reporters.
“For a young man to be sold an assault weapon at the age of 18 leads to this kind of tragedy,” he added.
Tuesday’s massacre in Texas elementary School in which 21 people including 18 children were killed was the worst at a US school since a gunman killed 26 people, including 20 children, at Sandy Hook Elementary School in Connecticut in December 2012.
More than 3,000 children and teens have been shot and killed and 15,000 more have been shot and injured since Sandy Hook, according to data from Everytown for Gun Safety, which tracks gun violence and other shootings on school grounds.
Meanwhile, US Congress has consistently failed to pass federal gun control legislation due to the influence of the powerful gun lobby.
