The total number of gang homicides reported by respondents in the NYGS sample averaged nearly 2,000 annually from 2006 to 2010. During the same time period, the FBI estimated, on average, more than 16,000 homicides across the US.

So the actual homicide rate is closer to 16k not 11k and the rate per 100k people is 4.8 not 4.2

Also the gang murders are 12%.

So 12% off 4.8 goes back to almost 4.2. Wow still 3.5 times that of UK.

If I was told to year a helmet that would make me die 3.5 times more likely then without it, I would be questioning the manufacturers motivation in proclaiming it was for my protection. I would also tell him were to shove said helmet and that I don't care for his scare tactics.
