The claim: Former WWII detention camps that are now converted into active federal prison complexes capable of holding several times their current populations. Alderson is presently a women's federal reformatory.
What it really is: Alderson was opened in 1928. It is minimum security, it has always been a Federal prison for women.
The Federal prison in Beckley is medium security with a minimum security prison camp.
There are no prisons in Lewisburg at all.
Also, none of these places were the sites of World War Two POW camps.
