Here is a little more info on the break down of how prisoners are segregated based upon levels of crime and risk.

Supermax Prison facilities provide the highest level of prison security. These units hold those considered the most dangerous inmates, as well as inmates that have been deemed too high-profile or too great a national security risk for a normal prison. These include inmates who have committed assaults, murders, or other serious violations in less secure facilities, and inmates known to be or accused of being prison gang members. Most states have either a supermax section of a prison facility or an entire prison facility designated as a supermax. The United States Federal Bureau of Prisons operates a federal supermax, A.D.X. Florence, located in Florence, Colorado, also known as the "Alcatraz of the Rockies" and widely considered to be perhaps the most secure prison in the United States. A.D.X. Florence has a standard supermax section where assaultive, violent, and gang-related inmates are kept under normal supermax conditions of 23-hour confinement and abridged amenities. A.D.X. Florence is considered to be of a security level above that of all other prisons in the United States, at least in the "ideological" ultramax part of it, which features permanent, 24-hour solitary confinement with rare human contacts or opportunity to earn better conditions through good behavior.

In a maximum security prison or area (called high security in the federal system), all prisoners have individual cells[106] with sliding doors controlled from a secure remote control station. Prisoners are allowed out of their cells one out of twenty four hours (one hour and 30 minutes for prisoners in California). When out of their cells, prisoners remain in the cell block or an exterior cage. Movement out of the cell block or "pod" is tightly restricted using restraints and escorts by correctional officers.

Under close security, prisoners usually have one- or two-person cells operated from a remote control station. Each cell has its own toilet and sink. Inmates may leave their cells for work assignments or correctional programs and otherwise may be allowed in a common area in the cellblock or an exercise yard. The fences are generally double fences with watchtowers housing armed guards, plus often a third, lethal-current electric fence in the middle.

Prisoners that fall into the medium security group may sleep in cells, but share them two and two, and use bunk beds[106] with lockers to store their possessions. The cell may have showers, toilets and sinks, but it's not a strictly enforced rule.[107] Cells are locked at night with one or more correctional officers supervising. There is less supervision over the internal movements of prisoners. The perimeter is generally double fenced and regularly patrolled.

Prisoners in minimum security facilities are considered to pose little physical risk to the public and are mainly non-violent "white collar criminals". Minimum security prisoners live in less-secure dormitories,[106] which are regularly patrolled by correctional officers. As in medium security facilities, they have communal showers, toilets, and sinks. A minimum-security facility generally has a single fence that is watched, but not patrolled, by armed guards. At facilities in very remote and rural areas, there may be no fence at all. Prisoners may often work on community projects, such as roadside litter cleanup with the state department of transportation or wilderness conservation. Many minimum security facilities are small camps located in or near military bases, larger prisons (outside the security perimeter) or other government institutions to provide a convenient supply of convict labor to the institution. Many states allow persons in minimum-security facilities access to the Internet.

They already segregate prisoners. Poor folks go to the state or federal pen.
Rich folks like Bernie Madoff go to country clubs.

I think the concern is having non violent people at constant risk of violence from violent people. Felonies are not all of a nature where someone brutalized anyone. Let the punishment fit the crime kind of deal. Allowing the non violent to 'serve time' with other non violent offenders, and violent offenders to 'serve time' with other violent offenders.

that could kind of excuse any inhumane consequence though, couldnt it?

You knew adultery was a crime worthy of stoning or beheading, so ,, you rolled the dice ...

You knew that joining the service could get you sent to an extremist area where you would be tortured so,,, you rolled the dice.

The reality of what is never should stop us from working on the reality that could (or should) be.

Well, according to others on the thread, there is something 'like' my daughters suggestion in place already.

IM glad to hear that breaking a rule or a law which has nothing to do with violence against others doesnt necessarily condemn one to a life of violent victimization.
