The chap does not deserve to be sniggered at, or to die for that matter, because he was momentarily stupid while drunk. Many many people are dead because they forgot to look one time when they stepped into a road. Are they stupid ? Sorry for my sense of humour failure here, but I take issue with the name of Darwin (who, by all accounts, was a really top bloke as well as a great scientist) being applied to this sneering and unfunny enterprise.
Oh and while I agree that America pays dearly for its rather mad gun laws, you can shove your received anti-americanism up your jacksee.
