Do you remember Colin Powell waving that tube of anthrax around at the U.N.? Or Bush Sr.s speech where he brandished his bag of crack cocaine that was sold right across the street from the White House (once government agents managed, with some difficulty, to lure the seller there)?
Gee, why werent Bush and Powell arrested?
A useful talking point: all laws against the mere possession of certain objects (guns, drugs, pornography, etc.) are a violation of human equality, because they inherently apply only to some people and not others (since the others the government have to retain possession of these items after they confiscate them, in order to use them as evidence against the original possessors).
