The price of keeping suspected terrorists at a detention center in Guantanamo Bay may be even higher than officials had estimated. According to a new report from the US Department of Defense, America will have spent $5.24 billion (pdf) on the prison camp between 2002, when it was opened, to 2014.
Guantanamo Bay is already said to be the most expensive prison in the world. Yet even the latest figure from the US Defense Department might not be high enough. The Miami Herald points out that total costs are likely to be higher because the Defense Department doesn’t take into account the facility’s $13.5 million headquarters built in 2004.
