US Attorney General Merrick Garland discussed a 400-page Department of Justice report with families of victims from the Uvalde school massacre.

The report criticizes law enforcement's response to the shooting, highlighting failures in protocols, communication, leadership, technology, and training.

These failures resulted in a delayed response and the deaths of 19 children and two teachers.

Families were disappointed with the meeting, demanding accountability and changes.

A separate criminal investigation is underway by local prosecutors.

Officers involved in the incident have been dismissed and lawsuits filed against the police and local officials.

President Joe Biden has pledged to implement the report's recommendations and address gun control.

The report particularly condemns school police chief Pete Arredondo for causing delays and holds him accountable.
