If you know an inmate in the Multnomah County Detention Center (MCDC) or the Multnomah County Inverness Jail (MCIJ) then this official 2012 inmate manual is a must print and mail. Inmates are not given copies of inmate manuals when they arrive and must borrow one from a guard to review jail policies. Sending them their own copy, even if it is an older version of the manual, could be very helpful. An inmate that knows the rules is less likely to end get written up.
I was fortunate to find this copy on top of the light in my cell when I moved it. It seems someone borrowed it, never gave it back, and the staff either did not look for it or considered it lost. I brought it home with me. Now you can have it by clicking on the above .pdf icon or link.
