They'd be wrong.

There's been no significant gun incidents | mass shootings, et al. of any real note in Australia since uniform gun regulation was introduced (matching the unregulated states and territories to those with regulation) following a world record breaking (at the time) mass shooting.

I'm in Australia, I have licenced weapons, my neighbour shoots ULR targets at 5,000 yards.

Gun regulation is great when properly implemented and it has demonstrably saved lives in this context.

You'd be correct to argue that uniform USofA wide simple clear evenly applied gun regulation would very likely be impossible due to the extreme difficulty of getting all states aligned and pulling in the same direction.

That's a different argument about a different challenge though.
