I've never supported the death penalty, however:

According to Texas law, felony murder is punishable by state execution. Due to Supreme Court rulings, a key component is acting with reckless indifference to human life.

There is the reckless indifference to human life.

These parents had the right to save their own children, and that right was denied because the police were too cowardly to risk themselves. Despite being on the scene before the shooter even entered the school, they held up the rescue for a full hour in order to wait for ballistic shields.

You can see parents being held back, some of them literally pinned to the ground. Tasers are out. On the parents of the fucking mass shooting victims.

Just under half of the victims survived. There's no telling yet how many more children would have survived if medical care could have been provided before they bled out in that classroom.

These are accomplices. To child murder. They directly caused more deaths by sheer cowardice, indifference, and assault on the parents.

The only potentially morally defensible use of capital punishment is on the violent actors of the state for extreme crimes against the populace, and it happens to line up with existing punishments on the books in Texas.

Will any US state, in this century, have the political will to even place one of these people on trial for child murder? Of course not. And adventurism is not only insane and immoral, it's also absolutely counterproductive. But it's absolutely within your right to advocate for the fair trial, appeals process, and lethal injection of every mother fucking pig on the grounds of that school.
