Jailed alleged Ponzi schemer Allen Stanford had been deemed incompetent to stand trial due to possible brain damage due to being severely beaten by another inmate and then subsequent addiction to anti-anxiety meds. The judge specifically said this does not mean he can be released on bail.
Unlike all other Ponzi schemers, Stanford was refused bail and incarcerated in Texas under what seems deliberately harsh conditions. If he was laundering drug cartel money, as some suspect, then there could be powerful forces who don’t want him saying anything in court, forces that could easily order him beaten up while in jail.
