It's not that the governement finds it out when the person die, they know all those things. They will only help when the president or a important minister in a big crisis wants to get popularity from the population. Like the way Joseph Kabila helped Ngadiadia Ngadios through his wife Olive Lembe. Another things is that organizing funerals of big musicians, comedians, politicans and soccer-players is very lucrative these days. You will notice that since 2007 there always problem about money, about x or y having stole money, etc.
