Mansfield Frazier says he is a former convict. He served his detention in a federal prison, according to him. He has written an opinion essay about what life will be like for Chelsea Manning in prison, which the Daily Beast has published, adding the following disclaimer:
This article is an opinion piece written by a former convict and based on his perceptions of life in federal prison. In its original version, it suggested that prison rape is rare. In fact, according to the advocacy group Just Detention International, 200,000 adults and children are sexually abused in American detention facilities every year. This trauma can carry serious emotional and physical consequences, including post-traumatic stress disorder, depression, and the risk of exposure to sexually transmitted infections.
I’m going to respond to Mr. Frazier, not form the point of view of a prisoner in a federal facility, but from the point of view I personally have. I’m a transgender woman who formerly worked at the United States Disciplinary Barracks at Fort Leavenworth, the facility that Manning will probably get to call home for the next substantial number of years.
Five years ago the San Diego County Sheriff, Bill Kolender at that time, issued a two-page “training bulletin” as guidelines for handling transgender inmates at local jails. The document provided Webster’s dictionary definition of transgender before adding the following:
The big news about transpeople is not something which is likely to help us win friends and influence people. On the other hand, the headlines are of some interest. 

I was asked by someone to recount some of my experiences working as a correctional specialist (aka prison guard) when I was in the US Army (1971-73). I decided to try to write about that for this evening, although those are not the easiest memories I have to work through, so there will probably be fewer stories than maybe I should have.
