\You do realize that the murder rate in prison is far lower than in regular world. It's not what people would like to think.
The number one reason people get the shit beat out of them in prison is because they owe money
Here is what I found from the Justice Department's website.
The homicide rate in state prisons fell from 54 per 100,000 prisoners in 1980 to 4 per 100,000 in 2002. Local jail inmate homicide rates fell slightly, from 5 per 100,000 in 1983 to 3 per 100,000 in 2002.
During 2002, the latest year for which such data are available, there were 978 jail inmate deaths and 2,946 state prisoner deaths from all causes. During the same year, suicides accounted for 314 jail inmate deaths and 168 state prisoner deaths. Fewer than 50 deaths in either local jails (20) or state prisons (48) were homicides.
During 2002, there was a higher homicide rate among the U.S. resident population (6 per 100,000) than either in state prisons (4 per 100,000) or in local jails (3 per 100,000). The rate of suicide in the resident population (11 per 100,000) was lower than in state prisons (14 per 100,000) and considerably lower than in local jails, which was 47 per 100,000 (average daily inmate population).
