The Robb Elementary School teacher is angry at the police in Uvalde because they stood by while the students were killed.

The teacher who was shot twice in his classroom spoke out for the first time. The students were told to lie under their desks and pretend to sleep after hearing gunfire.

The beginning of 77 minutes of carnage was when he saw the shooter. All of the students and two of the teachers died when it was over.

The police abandoned his students and he spoke directly to them. I don't have anything, you have a bulletproof vest. You are supposed to do your job. I won't forgive them for their actions.

He said that he felt bad for the parents because they lost a child. I lost 11 people that day.

He wants to be involved in the national debate about gun control and demand new legislation.

The only thing that I know is that I will not allow my co-workers to die in vain. I will travel to the end of the world to change things.
