Relatives of some of the May 24 elementary school shooting victims in Uvalde, Texas and survivors and parents of victims of other school shootings have spoken out against gun violence in schools. They said the frequent occurrence of school shootings in the U.S. has brought untold pain to people, called for stronger gun control and a background checks bill and blamed the U.S. government for inaction, which has allowed preventable tragedies to happen again and again.
