Blueblood,

The issue you raise certainly in the USA have come to the foreground of late, although it is unclear whether with any impact.

I know the BBC News had an item comparing several nations, but not readly found now. This four-sided discussion may help:http://www.bbc.com/news/world-us-canada-32740523

Obviously I am more familiar with the UK situation. As you show death from shooting here is rare. Deaths in custody alas are not and fatal road traffic deaths involving the police - even if lower now - can arouse controversy. Outside London and airports the numbers of armed police are low. My old force regularly deployed eight officers each shift, to respond to incidents; larger numbers were available for planned operations.

It is exceptionally rare in England for the police to be fired upon, even rarer are exchanges of gunfire between the police and others.

That is completely at variance with the USA. There are many reasons for this, which I expect have been exacerbated since 9/11 with the belief in a constant terrorist threat and a perceived increase in police readiness to shoot.

Then when one reads this, you start to wonder:
Data collected by the Washington Post newspaper suggests that the number of people shot by US police is twice as high as official figures claim. Official statistics rely on self-reported figures from law enforcement agencies.They suggest about 400 people have been killed each year since 2008.
