Very well.
To go back to this assault weapon, it's no wonder to me that we have this strange list and we have some guns on it, some not, and it doesn't seem to make sense to anybody. It doesn't make sense to me as a researcher, because to me, it would be based on the action of the actual rifle: Is it a semi-automatic rifle or a bolt-action rifle we're concerned with? Then are we concerned with the fact that most hunting rifles actually use high-calibre, high-velocity, high-energy projectiles that can cause serious damage? We're talking about those as if they're not a concern, yet these assault rifles, like an AR-15 that uses a small calibre, are somehow our big concern.
You need a better definition if you're going to do anything, and if your definition is whether semi-automatic rifle bans result in reductions in homicides, the answer is no. There's no good research that shows that from the United States, from Australia or from this country, so choose something else.
