I learned through a friend who was in immigration detention 9 years, and from others he encouraged me to visit, that the lot of immigration detainees is a hard one, with many hurdles, and with no (or few) helpful resources and people to help them. Many live with great fear and anxiety that they will be sent back to situations in their homeland which will be dangerous; they will be facing the wrath of the authorities, cruel authorities.
The laws and regulations that govern the cases of the immigration detainees are stacked against them. They are guilty unless they can convince their immigration judges that they are innocent. I attend one of these hearings; I saw this very thing. As a country we are certainly not living up to our stated ideal that all men are created equal.
