A Bit Thin?

When a Bail Application is being made the Prosecutor may put the Crown's objections to bail, such as fear of failure to surrender, commit further offences, or interfere with witnesses. Very rarely, and usually in the case of mentally disordered people, there may be an application to remand them in custody for their own protection.
The other day, opposing bail for a man accused of carrying a bladed article, the CPS suggested a remand in custody 'for his own protection' because if he went out again with a blade it might be used against him. We thought that was just a bit too thin.
