2) How could you possibly say that this definition of what constitutes interstate commerce is not overly broad? You could say a major portion of the traffic in ANYTHING flows through interstate and foreign commerce, and that incidents of the traffic which are not an integral part of the interstate or foreign flow, such as manufacture, local distribution, and possession, nonetheless have a substantial and direct effect upon interstate commerce, and that statement would be as valid as if you substituted the word "narcotics" for "anything" or "bicycles" for "anything." If you could make such a substitution and the resulting statement is equally as true, that, by definition, is an overly broad statement.
