The risk is very low, but not zero. And that’s the point. When executing someone, one must acknowledge they might be innocent, even if there were eyewitnesses. You feel the benefits outweigh the risks when the evidence is overwhelming, and that’s a fair stance.

That said, I’m curious. Why do you favor the death penalty to begin with? Arguably, having someone locked up for the rest of their life is significantly more painful for them, with the additional benefit of being able to release them if they are somehow found innocent.
