"Gun death rates in the U.S. were 11.2 per 100,000 people in 2015. That compares to a rate of 1.2 per 100,000 people in Australia."
Gun death rates is a pretty broad category. How many of those were suicides? How many were justified self defense? How many were gang violence in large metropolitan cities like Chicago, which already have strict gun control? We don't have that rate of gun death in Texas.
Why do you isolate gun death from other types of violent death? How does it compare to blunt instruments, stabbings, bare hands, vehicles, arson, etc? Murder is already against the law.
