Securing a client's release from jail in a federal criminal case is completely different than in state court. In state court a bond is almost always set by a judge shortly after someone is arrested. Then, at arraignment, you can usually persuade the judge to lower the bond.
Instead of posting financial bonds, federal judges generally either detain a defendant with no bond or they allow the person to post an unsecured bond which does not require any funds be posted. There is also a presumption in federal court that a defendant in a drug case or crime of violence case is a flight risk and/or a danger to the community. (18 U.S.C. Section 3142). These presumptions are rebuttable however, but still require the defendant's attorney to produce evidence first at a detention hearing.
It is important that defendants retain aggressive, experienced federal criminal defense attorneys at the earliest stage of a case. Careful planning, preparation and experience can make the difference between a defendant remaining in jail while the case is pending or being released.
