Suing the liquor stores is the next step. Shouldn't they be able to recognize habitual alcoholics (e.g., repeat customers)?
Already happening. My father once owned a lakeside resort/party store. On advise of his attorney, he quit giving out matchbooks with the store logo because they sold beer, wine and liquour. Seems the lawyer was representing a party store owner involved in just such a lawsuit over a drunk driver. No evidence they had even sold him beer, just the matchbook in the guy's car made the store culpable. Just Damn!!!!!!!
