Why do you think that? Please explain how the building just toppled like that.You say gas and fire,are you serious,fire doesnt cause a building to collapse at all,if anything it would have just burned. Why are you afriad to question your government are you that much of a sheep? Atleast investigate and find out on your own,because i was the same way but there were to many instances and to much corruption from this adminstration to just belive whatever they tell us.
