This is true of any punishment, though: if we want to hold people in prison, we're going to have innocent people in there too. Why draw the line specifically at "death"?
With capital punishment, we remove the possibility of fixing our mistake if someone is innocent. But if we lock someone up for 30 years, they have the opportunity for justice to be served, and we have mechanics to _try_ to make it right.
Right? Like if you run with the argument that people are making then we can't give people a life sentence because they may die in jail when they're innocent.
