It's not a "proposed bill," it's a bill. A bill by definition is a proposed law. If someone reads the word "bill" in a headline and confuses it for a law that has been passed, that says more about that person's lack of engagement in the basic workings of government (or more charitably, just momentarily inattentive reading) than it does about some supposed tactics. Anybody can fool themselves once by eliding the difference between "bill" and "law," but if it keeps happening, blaming the writers for being tricky seems a bit misplaced.
