Words fail me at this moment as I ponder the release of a nearly 600-page report chronicling the mass shooting at Robb Elementary School in Uvalde.

U.S. Attorney General Merrick Garland told the world Thursday of a systematic failure — from top to bottom — of the police response to the massacre of 19 children and two educators.

For 77 interminable minutes the cops did nothing while an 18-year-old lunatic was holed up in the school … and murdering children and the teachers who sought to protect them.

State troopers were present, along with Uvalde municipal cops, officers of the Uvalde school district, sheriff’s deputies. They were leaderless. They received no instruction to storm the school and take the shooter out.

The officers sat on their hands and allowed the carnage to continue.

I have no words of wisdom to offer. I cannot think of a way to prevent this sort of tragedy from recurring.

All I know is that the men and women who suit up as “leaders” failed to perform the essential tenet of leadership. They failed to issue orders to storm the school and do whatever it took to “neutralize” the moron who had purchased legally an AR-15 rifle and then used it to take the lives of innocent and precious children.

AG Garland took specific note that the AR-15 is intended for “the battlefield.” Its purpose is to kill people as quickly as people. It does not belong in the possession of individuals — such as the Uvalde madman — who then can rein havoc and mayhem on defenseless children.

How do we stop this madness? I have no clue on how one can do so while navigating the rough political water that so far has prevented any meaningful laws to curb such senseless violence.

Were I the King of the World, I might ponder whether there’s a way to amend the Second Amendment, the one that gun-rights advocates use as their political shield against solutions to the gun violence plague.

But I’m not. I am left only to gasp in horror at the findings of the Department of Justice and share the attorney general’s grief over the senselessness of the slaughter that no doubt will continue.
