Grieving Uvalde families condemn responding officers as 'cowards'

The officers who failed to tackle a shooter at Robb Elementary in Uvalde, Texas, for more than an hour should all lose their badges, relatives of some of the 21 people killed tell CNN.

"It was just like putting salt on an open wound," said Velma Duran, sister of murdered teacher Irma Garcia, of this week's assessment of the law enforcement response that revealed an armed police officer had an opportunity to shoot the gunman before he went inside Robb Elementary.

"It's hard to grieve when there's no closure," she said, six weeks after the massacre.
