Annie Yu points out: "As it now stands, we usually have to wait until a child breaks a law before we know that child has a problem. Only then can we plan corrective guidance. In actuality, the majority of children show signs in their behavior before they actually commit any crimes, such as running away from home, or playing truant from school.
余漢儀指出：「我們目前大多要等到孩子違法，才發現孩子出問題，而企圖矯正補救，其實，孩子在實際犯罪之前，大多可從他們的行為發現跡象，如逃家、逃學。
