Something like this (which I definitely don’t agree with): “Even though we don’t live under anything resembling a tyranny right now, it is possible in the future, for unforeseen reasons, that our government could become one. If we, unlike, say, the people of Syria, are heavily armed with very powerful weapons, we can prevent this oppression. Further, if assault weapons are criminalized and unavailable through the current avenues of attainment, a black market will develop and the money from such purchases can be funneled into other illegal activities. Yes, we fully understand our beliefs mean that sometimes these incredibly destructive weapons will fall into the hands of people who are mentally ill or criminal or domestic terrorists, and they will be used to harm and kill innocent people, causing great pain for their families and communities. As regrettable as this is, in the big picture we believe that a greater loss of life and liberty can occur if these weapons are kept from citizens.”
