AS is commonplace in Nigeria, we  have again witnessed another avoidable tragedy that has claimed lives - including children - and left many heavy hearted. ItaFaaji was not the first of its kind, whether in Lagos or in Nigeria, or the first where children are losing their lives. In fact, one could easily read a news item from one of the earlier collapses and it will fit right into the story of ItaFaaji. Lagos, particularly, has become a hub for collapsed buildings.
