I easily reconcile that: your examples are not purposeful. What you describe are accidents, not murder. Unless you're discussing terrorism, in which case, it would be purposeful. I'm discussing state sanctioned murder. And, yes, there have been cases of innocent people executed in this country. The most memorable to me is discussed in a book, May God Have Mercy, about a man convicted and executed in a murder in Grundy, West Virginia, later determined to be innocent. There are more but even if there weren't, one is one too many. Educated minds can and will disagree on this but, to me, even one innocent person executed is one too many.
