Lots goes on that we can't do much about. And when I say 'we', I mean those of us who are 'normal'. For some people, including really quite lowly politicians and celebrities, are treated as 'special'. Their lives are led under different rules than the rest of us. Special people need special treatment.
It is serious enough if police fail to investigate a major crime or mishandle something which leads to the deaths of innocent people - to then try to damage the reputation of the family and friends or the victims to cover up failings is a dreadful and cynical thing to do and we should not tolerate it.
