Stop being disingenuous, you're fooling no-one. Your 'deaths per gun' is completely meaningless unless no person owns more than one gun. Especially true if, as I suspect, you're a proponent of the NRA mantra that 'guns don't kill people, people kill people'. My personal take on that piece of bullshit is that 'people with guns kill people'.

The statistic that actually is relevant is the relative number of gun-deaths per year, pro-rated by population-size.

And a gun-death is a gun-death, irrespective of who the victim is. You might be interested to know that there have been a total of 68 fatal police shootings in the past 27 years in the UK - an average of less than 3 per year. How does that stack up against US numbers?
