It was later forwarded to several email lists, which is where I ran across it. Remember that, as far as guns go, the government, not criminals is the potential enemy. Hence, we should not let the government know who has guns, who has the ammunition. Political freedom is only secured by genuine power, and such power is ultimately secured only by force. For where a citizenry loses the ability to counter government force with an adequate force of it's own, it loses the ultimate guarantee of it's freedoms and rights.
Human freedom is always and only, threatened by other humans who are prepared to use force.
Against this threat, a wise citizenry will retain sufficient power to fight back, to fight any government that threatens its freedoms. The prime minister asks why we allow the registration of pets but are unwilling to register our guns. The answer is that we do not rely on cats and dogs for our freedom. Guns, however, are the essential tool of power, they are the fundamental tool of self-defence. The government knows that and keeps a good supply for itself.
