there were 2,788,000 traffic injuries in 2004, or 1,172 traffic injuries for every 100,000 registered vehicles on the road ...
there were 1,287,981 violent crimes in 2005, and while a cursory glance at the FBI Uniform Crime Reports reveals that the relationship of violent crime victims and offenders isn't reported, they do report the relationship of homicide victims to their attackers .... of 14,860 homicides in 2005, 2,070 (or about 14%) were committed by a "stranger" ... extrapolated to all violent crimes, there were about 180,000 "random" violent crimes ... this is an admittedly faulty approach, and i'm sure you could find a better statistic somewhere, but it's probably good enough to get a very rough estimate
the numbers aren't even close
and now i'm angry at myself for spending 5 minutes looking this shit up, thanks
