Answer is yes. Those who've proven themselves dangerous to society such as verifiably (not subjective) mentally ill and violent (as opposed to non-violent) felons. I don't think any reasonable person would argue with that.
Where we're heading with idiot legislation such as the AWB is that anyone a politician or liberal believes to be dangerous can have their human right of self defense stripped from them, which eventually will be everyone except for criminals, the elite and police. This is the dream of the anit-Americanist and we're letting it happen.
