As a practising lawyer, I see that peace bonds are often used as a way to get rid of criminal charges and that they are not enforced. They are of very limited value. There isn't a real follow-up.
A peace bond may be quite useful in dealing with a minor offence, or in the case of a person who, for example, got into trouble because of a drinking problem, just as an example.
Do we believe that a person who has committed the most horrible of crimes is going to be deterred by a peace bond? No. That is simply not going to happen. It is not an effective method to prevent a terrorist act from taking place.
