Well it doesn’t matter what lame opinions you have, because this case is going to get dunked right down the shitter so hard by the Supreme Court, that it will come out the other side in Australia.
But the fact remains that “assault weapons” are commonly purchased and used for self defense in America. You can argue about the merits of that all you want, but it is a fact that it is common in our current reality, and the judge was wrong. Personally I don’t own an AR, because they are impractical for everything I use a gun for.
