I think we are at a fundamental disagreement though; I think it should be expensive and difficult to execute someone. I think the slow appeals process is a good thing. It should hard for the government to kill people who aren’t a direct threat.
I don’t know your politics but it doesn’t matter the specifics. Imagine whichever politician that you think is most stupid and tyrannical. Do you really want to give them the ability to rapidly kill people they don’t like without at least some bureaucratic checks in place?
