To those all for banning guns, after literally 2 mins of googling I find reports that 'small arms' cause 500k deaths per year, 200k being civiliation deaths. Alcohol causes 2.5 million deaths a year. This is globally in both cases. Shall we ban alcohol too? Outlaw guns and only the outlaws have guns, and the government. There is nothing to say these nutters wouldn't have access to guns anyway. I would like to see more information released about the offenders back ground to be honest.
It's really quite funny that you have missed something massive, those 2.5 million deaths is what people are doing to themselves, with gun crime it's to others!
