Numbers are funny things. The Bolsheviks in Australia made semis illegal in 1996. Their murder rate in 1990 was about 2.2 per 100k. In 2018, it was about .90 per 100k. A 50+% reduction!!! Impressive, isn't it? Those gun grabbers must be oh so happy, I guess... and taking guns away from the subjects works!!!
Well, let's look at New Hampshire - the state where you don't even need a special permit or a test to carry. Just buy one and have fun any way want. And carry it concealed or on your head if you want. Yeah, but those horrible murder rates... OK, let's see how the cowboys behaved in NH...
1990 - 1.9 per 100k
2017 - 1.0 per 100k
Yes, those are the real numbers that actually match those in Bolshevik Australia where the subjects are now disarmed.
Almost forgot...NH has the highest number of machine guns per capita in the US. Yes, I mean those gifts from hell that can empty the mag in a couple of secs by just pulling the trigger once.
