The reason to lock him up now would be a to ensure he goes to his trial. Locking people up to punish them happens when they are guilty. Bail is denied only if there is a risk they will pose a significant danger or will not show up. The US government is in talks to extradite him, but he (allegedly) committed crimes in the Bahamas as well. There are legal proceedings going on now about who gets first crack at him. The Bahamas are keeping him from leaving the island so him fleeing isn't a major risk. It seems extremely likely he will end up in prison for decades. But it takes a while to prove the crimes to the court. Heck, they brought in the CEO who cleaned up the wake of Enron to try to get people their money back and the first thing he did was write a long letter tot he court about how they would need more time just to understand where their bank accounts were and how much money was in them because everything was so messed up records wise. The prosecutors need to be able to tell the jury specifics they are still gathering.
