Previously unreleased video, audio and interviews show for the first time how the medical response faltered after police finally confronted the Robb Elementary shooter.

This is heartbreaking. On the EMS side- there's been a push to change response and have training to wear vests/protection and actually go in right behind/with LEO/PD and treat as you go. There's been major improvement in getting transfusable blood out to the field (sounds like they had some in the helicopters). WTF?
Also communication issues have been known since WTC bombing, reinforced during 9/11. School and mass shootings- since Columbine. Again WTF??
