Why does it take decades to execute someone when there is video evidence that they are guilty?

My biggest objection to the death penalty has always been that the person might be innocent.

But here’s a video, from Tupelo, Mississippi, that shows a robber shooting a store employee in the head, after the employee had already handed over the money:

Here’s an article explaining that the guy has been arrested, and charged with capital murder. He could face the death penalty:

I hope this guy gets executed.

And I hope it doesn’t take decades.

I hope his execution happens before the end of this year.
