Lafferty on shooting and being shot at

Here is a quote by R. A. Lafferty about shooting people.

Here's another about being shot at:

When a man shoots at you once it can be an accident. When he shoots at you a second time he is still entitled to the doubt. But when he keeps it up the doubt gradually fades, and a certainty develops.

(R. A. Lafferty: The Devil is Dead)

Speaking of Lafferty, sfsignal has recently posted a link to a short story by him in Gutenberg titled "Sodom and Gomorrah, Texas".
