With details from the Uvalde mass shooting continuing to emerge, the region’s police officers are now coming under fire for reportedly delaying their entry into the school

It’s now believed gunman Salvador Ramos was inside Robb Elementary for up to an hour before he was killed.

The death toll stands at 21, with 19 children and two adults losing their lives.

This has prompted questions over whether authorities could have prevented some deaths if they intervened earlier.

Eyewitnesses say women and other onlookers were shouting at officers to “go in”, as they watched on in horror at the unfolding situation.

But authorities say the gunman had locked himself in a classroom, which made access difficult.

This comes as a daughter of an individual whose life was taken in the Sandy Hook massacre says the time to act on US gun violence was “ten years ago”.
