We never rule out that option. It depends on the case-by-case situation. In some cases, it's quite a good option, particularly for security certificate cases, in which we know they're going to be here for a while because they're going through litigation and court proceedings. In other cases, where removal may be imminent, a better solution, depending on the case, might be detention rather than putting them on a bracelet.
