There's been much talk lately about the death penalty, and it gives us another look at Death Euphemisms.
Look at headlines covering the execution of Stanley Tookie Williams. The LA Daily News, CNN and San Jose Mercury News both say it in one, bold word: "Execution". For CNN.com, NPR, and MSNBC, he was "put to death".
One obviously sounds softer. "Put to death" sounds like something you do to an old dog. It almost sounds like "put to bed".
Most outlets lean toward Execution. I agree. There's nothing soft about death by injection.
