Before anybody else leaps forward to put a calculated pejorative twist on it, let me mention that Earp shot a cowboy in the back.

The cowboy, expecting to make an easy dollar, had taken money to kill Earp. He flung a shot at Earp as he galloped past.

Earp whirled and shot him as he went by.

Nothing cold or calculated there!

But it'd be oh, so easy to say only that Earp shot an ordinary cowboy in the back.

"Good enough" isn't.

Always take your responsibilities seriously but never yourself.
