The correct answer is B: American jails
American jails have often been referred to as “the ultimate ghetto” as these jails continue to be the most neglected component of the criminal justice system. The people who have not been tried often remain in jail which is also known as the ultimate ghetto. The American jails hold a capacity of 750,000 in one single day. A "presumed innocence" pretrial detainee may spend several weeks at the same confined space with retained felons and troubled people.
