I completely agree that it does not absolve; after all, we arrest people for DUI.
I was more making an observation about the "partying" at conventions, and how it is a risk factor for this type of behavior and how we (as a society) often don't examine this.
I don't have any easy solutions, BTW. If there were easy solution, it wouldn't still be a problem. Maybe just the observation that going to a convention doesn't mean you get to drink yourself to oblivion without regard to the consequences to the people around you. And that conventions should be aware of problematic alcohol consumption.
Agreed totally - includ there are no easy solutions, and that they are likely society level. Individuals must take responsibility for their drinking habits and should not drink to excess in a public space, but that is not going to prevent bad actors.
Education and challenging people is gonna be needed.
