Palmer Luckey had an ... interesting perspective on it. I was against it before, and I'm still against it, but his point was that the killing of a citizen is one of the largest possible flexes that a state can exercise, and to prevent against its abuse it should probably be more visible to more people
I think that there is likely _enough_ visibility in the case of the classic execution, which is only done after the fifth amendment has been thoroughly exercised and appeals process fully depleted, and (ironically) not nearly enough visibility in the exercise of state power done by drone strikes and such, and so I take his point and appreciate it for what it is, which predominately is that I hadn't thought about it in that way before -- I still oppose the idea, but perhaps less strongly than before now that I know that bloodlust isn't the only viable interest (tho still a tremendous worry to me)
