Is there actually any evidence that the US does suffer more violent crime than the UK or indeed most other Western countries?
I too am American, but live in the UK.
The UK and the US record violent crime differently so it is difficult to compare the statistics. In the US violent crime is very well-defined and falls in to one of four categories: agro assault, robbery, rape and homicide. This is the definition of violent crime given by the FBI.
In the UK violent crime encompasses a much larger range of offences. You can go to the ONS website to find out what the list is, but it is a huge list of offences, many of which many wouldn't consider violent.
So it's hard to compare violent crime in the two countries.
What's easy to compare is the rate of gun deaths and homicides since the definitions are the same, and in both cases the US is much worse. One might be ok with the huge number of gun deaths in the US if the overall homicide rate was the similar (since that would mean that people are just killing each other with different weapons in the UK), but it's just not the case. The homicide rate in the US is much higher than in the UK.
The issue to gun control is there is an inherent distrust of the government, coupled to two polarized points of view.
but arguably this is where guns have failed americans the most. Ostensibly the reason for having guns is to keep a tyrannical violent government in check Yet American police kill over 1000 people a year. It wouldn't surprise me if police in the UK haven't killed 1000 people in a span of a 100 years.
