The agency was established in 2003
Its responsibilities are to raise awareness for the violence of prison rape and try to prevent further cases by passing laws and providing people with the knowledge to realize something is happening.
Currently the committee is trying to make prison rape not be a common occurrence and their most recent high profile example is Dylan Roof.
There is no market in prison rape so they must provide all of the tools and awareness regarding the raping of prisoners.
