How many of them are out on bail?
None I hope!
Once the detainees are faced with legal consequences of their crimes AND they comprehend the requirement for payment on damages... maybe, they will TALK about their paymaster and the others, who have ‘deployed’ them.
Not one of them should be released until/unless they provide that information. It’s certain that they are not ‘salt-of-the-earth’ representatives of the ‘downtrodden’ or selfless Crusaders for ‘justice’.
Without avowal of a connection to organized crime, then they are admitting perpetration of the crimes in their OWN name and can take the consequences, personally. PERIOD!!
Let them out on bail. By the time they pay a bondsman and retain a lawyer, they’re going to be out several thousand dollars.
When it comes to bond, federal court is substantially different than state court. There is no "cash bond" in federal court (except in VERY rare cases). Either the government moves to detain pre-trial or they do not. If they move to detain, then there will be a detention hearing held and the judge will either order them detained, or let them out on their own recognizance. If released, then they will be under supervision of the pre-trial services office. If they screw up on pre-trial release, they will likely be detained.
A lot of this depends on what they are charged with as well if the government will move to detain or not. As far as lawyers go, if they can't afford one they will either be represented by the federal public defender's office or a private attorney will be appointed to represent them.
