Actually in a legal sense that is not correct. A court can hold someone in custody for a serious matter, usually because of fear of flight or of the person committing further offences, given his criminal history. There are clear guide lines for bail, and bail is aimed at ensuring the person attends court to answer to the charges, not because he or she is deemed guilty. Often bail is refused because the person has had previous matters where they have taken flight, and has a serious history of offending, or the material supplied by the police in the initial hearing or even a mention, is such that the magistrate is convinced that there is a strong probability of guilt. And of course if the offender is charged with an indictable matter that can only be dealt with at district court, and has pleaded guilty, the person would obviously be held in custody. But in all cases it is the judiciary that makes that decision, not the public, employers, media etc
