Bingo! But, if you REALLY want to stop it, the ONLY thing that would work to make "enforcement" efficient/viable are stiff fines for first offenders, and mandatory jail sentences for the second offense.
Put some soccer mom's high school kid in jail for thirty days, and it wouldn't take long for the ADD generation and their spawn to get the point.
Too damn bad the warm fuzzy liberal judges, the ultimate political appointees of the very folks screaming the loudest in favor of the laws, won't do that.
A perfect example of the built-in inconsistencies in warm fuzzy thinking ...
