It is often said that rules are made to be broken. Some rules seem more breakable than others.
For example, I'm pretty sure that the speed limit on the Scottsdale leg of Loop 101 is but a mere suggestion. And I have an inkling that not all of the, ahem, herbal medicine prescribed these days isn't strictly used for its written purpose.
Through American history, one of the most noteworthy times that rules were broken left and right was during Prohibition. Even though the manufacture of alcohol was illegal, it didn't stop much of society from getting a drink.
