Free speech is not to be regulated like diseased cattle and impure butter. The audience that hissed yesterday may applaud today, even for the same performance.

William O. Douglas
[A similar thing can be said of guns. The type of gun that was used for a terrible crime yesterday may be used to save many lives the next. The government that protects you one day may next year send you to the gulags--unless you and your kind own and know how to use guns.--Joe]
