Let me spell it out for you.
It means for every 100,000 people ya got in Richmond, there are 38.8 murders. In LA there are only 12.4 for the *same* amount of people.
No matter how ya chop it up, this is mind boggling and means the degree and frequency of crime occurring in Richmond Virgina makes Los Angeles look like a church picnic.
You seem to have a reading comprehension problem. I gave you a link to an article about the gang and racial wars going on in LA. This is more than just crime rates, which don't tell the whole story.
There is no doubt that statistically Richmond has a higher crime rate per capita than LA. Of course LA's population is 3,879,455 compared to Richmond's 195,708. If you compare LA to NYC, LA has a much higher crime rate per capita with almost twice the murder and forcible rape rates.
The bottom line is that LA is becoming a third world city due to a huge influx of immigrants, legal and illegal. The gap between rich and poor, failing schools, increased welfare rolls, corruption, and out of control gangs mark a city in decline.
