"In Uvalde, the shooter was 17 when he asked his sister to buy him an assault weapon, knowing he’d be denied because he was too young to purchase one himself. She refused. But as soon as he turned 18, he purchased two assault weapons for himself. Because in Texas, you can be 18 years old and buy an assault weapon even though you can’t buy a pistol in Texas until you’re 21. If we can’t ban assault weapons, as we should, we must at least raise the age to be able to purchase one to 21."
