Frequently in scenarios where there's a risk, but then what are the actual stats behind that?
For example, there's this which has assaults on officers in 09/10, across most police forces,

With Avon and Somerset, there were apparently 2873 police officers as of March 2013... and I'd guess that number isn't larger than in 09/10. Anyway, that means 0% of them died, 0% of them had a serious injury, and 0.056% of them had a minor injury or no injury after the assault.
Essex with 0%, 0.0003%, 0.091%
The Met with 0%, 0.005%, 0.052%
South Wales with 0%, 0.012%, 0.044%
I did Avon and Somerset because it was first, but then a few with higher looking numbers so I wasn't accused of picking the best, or something.
I'd be interested to see that compared with other professions - eg. traffic wardens, nurses, etc.
