She probably didn't think it was appropriate for ICE to arrest Ruiz at the courthouse. If going to court for a case against you becomes a good way to get deported, guess what people aren't going to do. We don't have the resources to keep everyone who has a case against them in jail, so we release people on the promise that they will show up for court. If it's dangerous to their freedom and living status to show up to court, they won't.
