RE: Drinking and Flying
This is what the LAW says
Section 34 of Chapter 62, Laws of 1933 (RCW 66.44.100) prohibiting the opening of packages containing liquor or consuming of liquor in a public place, except as provided by the Liquor Act, has not been repealed, either expressly or by implication.
NOW think about it !!! If any one drinks in public places are breaking the law !!!! :-)) Hence, You can simply call the police.
Sorry guys a few words of advice from a lawyer.
