Why can't America figure out how to kill Death Row inmates?

I vaguely followed that shit-show in Alabama, where the state felt compelled to experiment with nitrogen gas as a mode of execution. By all reports, this experiment did not show the way forward in humane executions. Here’s a thought. There’s a “toxic drug” epidemic raging across America. People are dropping dead from coast to coast due to the fentanyl crisis. This shit is 100x more potent than heroin. Back in the day we had a heroin epidemic. Addicts had to steal a hundred bucks worth of stuff to get their next fix. Today a hit of fentanyl can be had for a dollar or less, from what I’ve seen on the news. No wonder people get wasted and stay there. They can afford it! But that’s another issue. My point is this. If humane execution is the goal, just leave a jug of Jack Daniel and a bag of fentanyl pills with death row dude at the last supper. He’ll be gone by morning.
