Sri Lanka hurriedly banned mobile phones at schools, not just for students but teachers as well, following a suicide of a Museaus girl, allegedly after an incident involving a mobile phone. Pity that they never reflected on the other side of the story. Mobile phone is a security device that enables critical communication between parents and children. Take it away and the results can be disastrous because that makes a child vulnerable. Take the story of Lasantha Gimhana Kanewela (10), for example.
