I can't wait till one of the stumblebums walks out, gets in his car and runs down another patron two blocks from the bar and then the lawyer for the dead guy's family gets the undercover cops on the stand and asks them to explain why they let this obviously impaired killer drive off to do the dirty deed.
You beat me to it! If a family member is hit/injured by a drunk driver observed by police waiting for a big $$ DUI charge instead of a public intox charge, there is police liability, and should result in large judgments against the police. Hopefully, the 1st large judgment against police should put a stop to this. Otherwise it is time to start Neighborhood Watch patrols of "cop bars".
