Murders with guns

I saw someone post this on Facebook, I thought it was a good idea to post it here too. Take note, I live in Canada This was obviously written by someone living in the US.

America currently averages 14,500 murders a year. Of those, 9,000-11,000 are gun deaths. We have over 300 million guns for a population of over 300 million. That's about 70% of the murders being performed with a gun.

The UK averages 800 murders a year, with about 50 a year from guns. They have a population of 60 million. Handguns are banned in the UK, and rifle or shotgun ownership requires a lot of registration and paperwork. There are about 3.4 million guns in the UK. That's about 7% of the murders being performed with a gun with an average of 4 murders performed with a handgun per year.

Japan has about 650 murders a year. They average 37 gun homicides a year. Japan's population is about 125 million. Handguns are completely banned in Japan, and shotguns or rifles are strongly regulated. There are about 700k guns in Japan, most of which are shotguns. That's about 6% of the murders being performed with a gun. Handguns averaging between 0 and 1 deaths per year as the tool used.

Why do they only kill between 10-30% of the people Americans do each year?

Do Americans just get angrier than the Japanese and the British? Are we just a bunch of hotheads who kill people more readily than folks in these other countries, regardless of what tool we use to kill them with? (Mark Martinez Blog)
