A second opinion is all well and good, but maybe drunk passengers should be offloaded by the ground staff without involving the pilot in the decision? He's got enough to do. If there's a group in the bar who are clearly not compis-mentis enough to fly, have their baggage put on standby, call airport security and senior staff as back-up and tell them when they get to the gate that they won't be travelling. Then the flight can depert safely and on time....
